We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. Abstract. Among these cases, 2 cases showed a fracture around the ganglion [7, 8] and only 1 case was accompanied with suprascapular nerve entrapment, which is similar to our case [9]. Additionally, the previously reported case of an intraosseous ganglion accompanied with suprascapular nerve entrapment was treated with needle aspiration under arthroscopy [9], and posterior shoulder pain and muscle strength weakness of the shoulder resolved. This article describes an arthroscopic technique used for lunate intraosseous cyst resection associated with an autologous bone graft in a series of cases to prevent joint stiffness while respecting the scapholunate ligament. Two main types of periarticular cysts are frequently seen on shoulder MRI, both of which have a strong association with underlying abnormalities. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. Ganglion cysts are fluid mass that most often develop over the tendons and joints, usually the wrist and fingers. The nerve was stretched and edematous, and it highly adhered to the cyst wall. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. Tam W, Resnick D, Haghighi P, Vaughan L: Intraosseous ganglion of the patella. It has a stalk through which fluid enters in the lump. Notice the intermediate signal within the cyst, suggestive of pannus invasion. Ganglion cysts are also common in people having osteoarthritis of shoulder. A 10 cm skin incision is made at the posterior glenohumeral joint. Plain radiographs show an eccentric intraosseous radiolucent lesion that should be differentiated from osteoarthritic cyst, post-traumatic cyst, simple bone cyst, osteoid osteoma, or osteoblastoma. We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. Only 13 cases around the shoulder have been described in the literature. [1-7] While the medial malleolus and proximal femur are the most common sites, intraosseous ganglia of the glenoid have been reported in only 11 patients. The treatment options include rotator cuff repair, excisional AC joint arthroplasty and resection of the cyst base, aspiration, hemi‐arthroplasty, and reverse total shoulder arthroplasty 1. Therefore, we concluded that the protrusion of an intraosseous cyst of the glenoid into the spinoglenoid notch was a cause of the pain, and performed curettage. They are lined by fibrous tissue with myxoid change and are not associated with osteoarthritis in the adjacent joint. Clinical Features: An 18-year old female flat water canoeist complaining of right shoulder pain following a strenuous paddling training camp. Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. Intraosseous ganglia within the carpal bones are relatively rare, with only a limited number of cases previously reported (1–3).They are benign, non-neoplastic bone lesions that have similar histological characteristics to those of soft tissue ganglion cysts (4,5).The most common clinical symptom is wrist pain. Other locations include the finger, palm of hand, wrist, elbow, shoulder, hip, knee, ankle and foot (Fig. People who have shoulder injury in the past are likely to have ganglion cysts in shoulder. Plain anteroposterior radiography of the left shoulder showed a circular lesion with marginal osteosclerosis at the glenoid (Figure 1(b)). The suprascapular nerve was raised upward by the cyst wall present below the nerve. Here, we present a case of suprascapular nerve entrapment caused by an intraosseous ganglion in the glenoid, which was treated with curettage of the ganglion.

We are committed to sharing findings related to COVID-19 as quickly as possible. Epidemiology Tends to occur in middle age. The aim of this study was to investigate the characteristics of cysts in the tuberosities of the humeral head and their relationship with rotator cuff tear and age. Surgical treatment of this pathologic condition yields good results and a low recurrence rate. Intraosseous ganglia are intramedullary, non-neoplastic, subchondral cystic lesions containing mucoid fluid. A lipoma, which feels doughy and usually isn't tender, moves readily with slight finger pressure. The most common is the paralabral cyst that results from a glenoid labral tear . The patient’s posterior shoulder pain resolved after successful curettage of the ganglion. The suprascapular nerve was retracted gently, and curettage was performed until the bone surrounding the cyst was completely exposed (Figure 3(d)). The cysts were curetted and filled with artificial bone (β-TCP). with intraosseous ganglia of carpal bones. Clinical presentation Patients may have mild localized pain. Histological examination revealed that the cyst wall contained connective tissue, including … These findings were consistent with an intraosseous ganglion. Up to 7cm in size, usu. Mean average age of patients is 42 years. The cysts were … J Hand Surg 17B:429-32,1992. Computed tomography (CT) showed a circular cystic lesion with marginal osteosclerosis and cortical bone destruction of the posterior glenoid at the spinoglenoid notch (Figures 2(c) and 2(d)). An intraosseous ganglion (plural: ganglia) is a benign subchondral radiolucent lesion without degenerative arthritis. It can be symptomatic in A 47-year-old female patient presented at the Cankiri state hospital complaining of pain and restricted motion in the righ arm since 2 months. They often recede in the size and sometimes disappear. Another theory put forward suggests a flaw in the joint space which allows the tissue to protrude out. An extraosseous cyst was located over the posterior glenoid neck, which had capsules filled with a transparent gelatinous substance. Biodegradable implants lead to problems such as cyst formation, soft-tissue inflammation, loose implant fragments or local osteolysis. An intraosseous ganglion is a benign bone lesion but is considered a neoplasm, which is similar to a ganglion occurring in soft tissue [3, 4]. Some people have more than one lipoma.A lipoma isn't cancer and usually is harmless. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. The cyst of the shoulder girdle in most cases is diagnosed as an aneurysmal, solitary cysts in this zone are formed only in 20-25% of patients. They often recede in the size and sometimes disappear. We reported a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch, which is a rare cause of posterior shoulder pain. The cyst is removed with arthroscopic procedure. First, based on the radiographic finding of bone cortex destruction at the spinoglenoid notch, the differential diagnosis included an intraosseous ganglion, giant cell tumor, aneurysmal bone cyst, and chondroblastoma [12, 13], so we needed a specimen to perform histological examination. Tuzuner T: Penetrating type intraosseous ganglion cyst of the lunate bone. We present the first reported case of complete, spontaneous resolution of a massive AC joint cyst without the need for surgical intervention. We experienced a rare case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. These cysts should be considered causes of unexplained rotator cuff weakness in young patients, although they may also be discovered incidentally on MRI. It requires an MRI or MR Arthrogram to find out if it is as a consequence of a paralabral cyst. On magnetic resonance imaging a cystic lesion of the proximal humerus was detected. Subchondral cysts are of variable size from a f… The area includes the supra- and infraspinatus muscles and the suprascapular nerve. These cysts commonly occur between 20 to 40 years of age. Annals Of Orthopaedics, Trauma And Rehabilitation. MRI of the shoulder has proven to be an accurate noninvasive examination for the evaluation of patients with shoulder pain. GROSS PATHOLOGY. The suprascapular nerve is a mixed motor and sensory nerve originating from the brachial plexus. After the operation rehabilitating exercises will help the shoulder to perform all movement. (a, b) Microscopic section of the cyst wall shows that the wall contained connective tissue, including collagen fibers and a few fibroblasts, and that the inner layer of connective tissue had myxoid change. Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. with intraosseous ganglia of carpal bones. INTRAOSSEOUS GANGLION. Furthermore, in surgery, we could identify the intraosseous cyst and suprascapular nerve and protect the nerve under direct vision; nevertheless, the intraosseous cyst compressed the nerve and adhered to it causing edema. (b) Intraoperative photograph of the posterior shoulder shows the suprascapular nerve after splitting the infraspinatus (yellow arrow). This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. Postoperatively, the patient’s shoulder pain resolved promptly. Suprascapular nerve entrapment is an uncommon but significant cause of shoulder pain [1], and a ganglion originating from the soft tissues around the spinoglenoid notch has been reported to be a cause of suprascapular nerve entrapment [2]. The patient gave informed consent and permission for this publication. As a result, we could perform curettage of the cyst wall, which relieved the patient of the symptom. About 2-4% of the general population is likely to have it and presentation may be common in males (especially around the third to fourth decade… We believe that open surgery including curettage is a useful treatment option for a ganglion inside bone and present very close to the suprascapular nerve. ... Intraosseous operation - resection of the cyst with parallel bone graft and application of Ilizarov's apparatus. In such cases surgical intervention may be necessary. An extraosseous cyst was located over the posterior glenoid neck, which had capsules filled with a transparent gelatinous substance. showing intraosseous cyst. Introduction. Ganglion cyst in shoulder is not common, but when present can produce discomforting pain and weakness in shoulder. Only 13 cases around the shoulder have been described in the literature. First you have to confirm it simple bone cyst or not. Osteoarthritis and rheumatoid arthritis can lead to the development of these cysts… The site was then injected with a small amount of demineralized bone matrix. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. However, treatment is required if this non cancerous lump causes pain in shoulder or difficulty in movement. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. This report describes a case of an intraosseous ganglion about to cause fracture of the glenoid. Abstract Intraosseous ganglia are benign cystic and often multiloculated lesions composed of fibrous tissue with extensive mucoid changes located in the subchondral bone adjacent to … The cyst is just underneath the skin near a joint. It is more prevalent in men. Intraosseous ganglia are rare lesions that can cause pain and leave patients susceptible to pathologic fracture. The cyst can range in size and it can be as small as a pea or as large as a marble. These lesions are often asymptomatic, but, in cases located close to neurovascular structures or articular surfaces, they can be symptomatic, causing pain, neurologic dysfunction, or articular fractures. Clinical presentation Patients may have mild localized pain. Intraosseous ganglion cysts are rare causes of hand and wrist pain. A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. Design and patients: Shoulder MR arthrograms were reviewed in 120 consecutive patients-83 males (mean age 38.0, range 19-59 years) and 37 females (mean age 41.2, range 15-59 years). Second, needle aspiration or incision under arthroscopy was speculated to be arduous because the main part of the ganglion was located inside the glenoid and it was apart from the glenohumeral joint cavity. Ganglion cyst in shoulder is not common, but when present can produce discomforting pain and weakness in shoulder. Intraosseous rheumatoid nodules are rare; however, they have been described in patients with rheumatoid nodulosis [21–23]. Patients were referred for investigation of a variety of conditions, and instability was suspected in only a minority of cases. 1). Ganglion cysts can decrease or increase in size and sometimes they disappear completely. These cysts are produced in areas of damaged articular cartilage, subjacent to the underlying subarticular cortical plate. The patient was a 61-year-old woman with a painful left shoulder with a limited range of motion. Pain relievers may be beneficial in alleviating shoulder pain. The area was drilled and a curette was used to remove any material but little was extracted. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. In the absence of nerve compression symptoms it is a tad difficult to zero in on the diagnosis unless there is an image that supports the diagnosis. pain is due to an intraosseous bone ganglion cyst. Needle aspiration for the cyst was performed using an 18-gauge needle under ultrasonographic guidance; however, no aspirate was obtained. A skin incision of approximately 10 cm was made along the glenoid on the lateral side of the scapula. Intraosseous ganglion cysts are very frequent in the carpal bones, located at the attachments of degenerative ligaments 5. Intervention and outcome: A trial of passive care was conducted, including Postoperatively, the patient's shoulder pain resolved promptly. Review articles are excluded from this waiver policy. … Only 13 cases around the shoulder have been described in the literature. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. A subchondral cyst is an intraosseous epiphyseal synovial fluid-filled void prevalent in osteoarthritis that may attain a diameter of 1-15 mm or more in size with the cyst’s longest axis usually along the coronal plane in the craniocaudal axis. Certain factors increase the risk of ganglion cysts. Ganglion cysts can decrease or increase in size and sometimes they disappear completely. This report represents the first published case of an intraosseous foreign body granuloma in the humeral head after arthroscopic rotator cuff tear fixation with a poly-l-lactide (PLLA) suture anchor. May extend through the cortex into the joint, esp. 2019; 2(2):133. posterior to the anterior horn of medial meniscus (Figure 4) . Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. Thus, the intraosseous cyst was considered to be an intraosseous ganglion. However, it is a significant diagnosis as they may cause a compression neuropathy of the suprascapular or axillary nerves depending on where they occur, along with a variety of other symptoms. Epidemiology Tends to occur in middle age. Besides, anti inflammatory medicines may also have side effects if they are taken for long time. Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. Suprascapular Nerve Entrapment Caused by Protrusion of an Intraosseous Ganglion of the Glenoid into the Spinoglenoid Notch: A Rare Cause of Posterior Shoulder Pain, Department of Orthopaedic Surgery, Gifu University School of Medicine, Yanagido 1-1, Gifu, Gifu Prefecture, Japan, R.

Abstract We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. Intraosseous ganglion cyst References [1] Adam Greenspan, Gernot Jundt , Wolfgang Remangen (2007) Differential diagnosis in orthopaedic oncology. The histological finding was an inner layer of fibrous connective tissue without any lining cells. Skeletal Radiol 25:588-91,1996. Nusselt T(1), Freche S, Klinger HM, Baums MH. Usually ganglion cysts do not require to be treated if they do not produce any symptoms. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. To our knowledge, 19 cases of intraosseous ganglion of the glenoid have been reported in the English literature [4–10]. Author information: (1)Department of Orthopaedic Surgery, University of Göttingen, Medical Center, UMG, Germany. The most common is the paralabral cyst that results from a glenoid labral tear. This compression can result in atrophy of the supraspinatus or infraspinatus muscle or both. Only 13 cases around the shoulder have been described in the literature. Based on the findings of MRI and CT, an intraosseous ganglion, cyst of degenerative disease, giant cell tumor, aneurysmal bone cyst, and chondroblastoma of the glenoid were suspected. It passes between the suprascapular notch and superior transverse scapular ligament into the posterior surface of the scapula, which dominates the supra- and infraspinatus muscles. Ganglion cysts typically form within deep tissue as one or a cluster of smaller cysts connected by a common stalk. At the 1-year follow-up, the patient was asymptomatic and had no functional deficits and osteoarthritic changes of the glenohumeral joint were not observed on CT, but recurrence of the ganglion was observed at the glenoid on MRI. The cysts may be the result of mucoid degeneration in the adjacent ligament, or both the degeneration and … Annals Of Orthopaedics, Trauma And Rehabilitation 03 Arthroscopic Management of an Intraosseous Ganglion Cyst in the Prox imal Tibia. (b) MR T2-weighted sagittal image of the left shoulder shows that the intraosseous lesion is linked to the spinoglenoid notch. The extraosseous cyst extended to the intraosseous lesion directly. However, only 11 cases of intraosseous ganglia of the glenoid have been reported. Biodegradable implants lead to problems such as cyst formation, soft-tissue inflammation, loose implant fragments or local osteolysis. Few reports have presented the characteristics of an intraosseous ganglion, such as its incidence and etiology, and this ganglion is considered to be relatively rare. An intraosseous ganglion (plural: ganglia) is a benign subchondral radiolucent lesion without degenerative arthritis. A 48-year-old female patient presented with pain in her right shoulder. Lipomas are usually detected in middle age. On visiting our hospital, he complained of continuous posterior shoulder pain at rest; however, he could move his shoulder actively at 160 degrees of flexion and abduction, 60 degrees of external rotation at the side, and 90 degrees of external rotation at abduction and could maintain muscle strength around the shoulder on manual muscle testing. (b) Radiograph of the left shoulder shows a radiolucent cystic lesion in the superior glenoid. These lesions are often asymptomatic, but, in cases located close to neurovascular structures or articular surfaces, they can be symptomatic, causing pain, neurologic dysfunction, or articular fractures. West Indian Med J 54:247-9,2005. The operative findings showed a 1.5×1.0 cm size supraspinatus tear and an intraosseous ganglion which had transparent jelly contents. The exact reason why a ganglion develops in shoulder is not known. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. A ganglion cyst is diagnosed during physical examination if it is on the shoulder. This report represents the first published case of an intraosseous foreign body gran-uloma in the humeral head after arthroscopic rotator cuff tear fixation with a poly-L-lactide (PLLA) suture anchor. (a) Magnetic resonance (MR) T2-weighted axial image of the left shoulder shows a high intensity area at the glenoid. 28-194). We performed curettage with protection of the suprascapular nerve, and the patient’s pain resolved completely without suprascapular nerve complications. Thus, the intraosseous cyst was considered to be an intraosseous ganglion. People who are prone to do repetitive movement of shoulder are more susceptible to develop ganglion cysts in shoulder. Two main types of periarticular cysts are frequently seen on shoulder MRI, both of which have a strong association with underlying abnormalities. A small incision was made in the anterior shoulder, the cyst site was identified due to a small hole noticed in the bone deep to bicep tendon. Therefore, in the present case, it was believed that the ganglion did not occur in the soft tissue around the spinoglenoid notch and then penetrate into the glenoid, but it occurred primarily inside the glenoid and protruded into the spinoglenoid notch accompanied with bone destruction over a long period. 24) is an intraosseous cyst which occurs beneath an articular surface of a bone. All the authors certify that they have no commercial associations that might pose a conflict of interest in connection with this report. Small intraosseous cysts (yellow arrowheads) typically form at the anterior margin of the femoral attachment of the ACL and at the posterior margin of the distal attachment. This study was approved by the Human Ethics Committee of Gifu University (no. Histological examination revealed that the cyst wall contained connective tissue, including collagen fibers and a few fibroblasts, and that the inner layer of connective tissue exhibited myxoid change (Figures 4(a) and 4(b)). A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. Wrist arthroscopy is a surgical technique that reduces the intra-articular operative area and therefore minimizes postoperative stiffness. Intraosseous ganglion cysts are rare causes of wrist pain. Figure 3: MRI of the knee joint T2 Image (a) and (b) showing periarticular intraosseous cyst. An intraosseous ganglion/ cyst, however, is not common and is limited to the hip, knee, and ankle.5 In particular, an intraosseous ganglion of the glenoid is extremely rare, and no study to date has reported on an intraosseous glenoid ganglion /cyst. However, the ganglion relapsed at the 1-year follow-up on MRI, suggesting that curettage for the ganglion was inadequate and en bloc resection would be necessary if the symptoms of the left shoulder recur. However, if the cyst is inside the shoulder joint certain tests such as ultrasound, MRI, may be required for its diagnosis. (c) Intraoperative photograph shows a mucinous cyst wall after shifting the suprascapular nerve laterally. Intraosseous foreign body granuloma in rotator cuff repair with bioabsorbable suture anchor. Recently, a simple and safe less invasive arthroscopic approach was reported for patients with spinoglenoid ganglion cysts [11]. This study was based on a series of 4 patients, all of whom had wrist pain because of intraosseous ganglion cysts. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. After releasing the nerve gently from the cyst (Figure 3(c)), an incision was made at the cyst wall, and gelatinous material flowed out from the cyst. Intraosseous ganglia are uncommon in skeletal sites such as the carpal bones, wrist, proximal femur, distal tibia, and glenoid bone. Recently, a simple and safe less invasive arthroscopic approach was reported for patients with spinoglenoid ganglion cysts [11]. Patients suffering from paralabral cyst have chronic shoulder pain as the chief complaint. Curettage was performed under general anesthesia in the right lateral position (Figure 3(a)). (d) Intraoperative photograph shows the bone cavity of the glenoid after curettage of the cyst (yellow arrowheads). However, ganglion cysts in shoulder may … Brantley et al. A subchondral cyst is an intraosseous epiphyseal synovial fluid-filled void prevalent in osteoarthritis that may attain a diameter of 1-15 mm or more in size with the cyst’s longest axis usually along the coronal plane in the craniocaudal axis. In our case, we used curettage and did not consider arthroscopic treatment for various reasons. A ganglion cyst is diagnosed during physical examination if it is on the shoulder. A 47-year-old man with left shoulder pain lasting for more than 2 years was referred to our hospital because a radiolucent cystic lesion of the glenoid was observed on plane radiography of the left shoulder. Treatment generally isn't necessary, but if the lipoma bothers you, is painful or is growing, you may want to have it removed. dysfunction caused by an intraosseous ganglion of the glenoid is extremely rare, to the best of our knowledge, only 1 case of suprascapular nerve entrapment due to an intraosseous ganglion cyst has been reported previously in the published literature. The patient was a 47-year-old woman with a painful left shoulder with a limited range of motion. Intraosseous ganglia are uncommon in skeletal sites such as the carpal bones, wrist, proximal femur, distal tibia, and glenoid bone. Therefore, curettage of the cyst was performed. @article{Yi2009IntraosseousGO, title={Intraosseous ganglion of the glenoid causing suprascapular nerve entrapment syndrome: a case report. However, if the cyst is inside the shoulder joint certain tests such as ultrasound, MRI, may be required for its diagnosis. Objective: To present the diagnostic and clinical features of an intraosseous ganglion cyst of the humeral head of a female flat water canoe athlete. Axial (12a) and coronal (12b) proton density-weighted fat-suppressed images of the shoulder reveal a large intraosseous cyst (asterisks) in the greater tuberosity. Intraosseous ganglia are uncommon in skeletal sites such as the carpal bones, wrist, proximal femur, distal tibia, and glenoid bone. The main complications are joint stiffness and vascular disturbances of the lunate bone. Intraosseous ganglion (IOG) cysts of the humerus is a rare and often painful condition.5–9 There is only one other case in the literature describing an IOG cyst of the humerus, while most papers describe cystic lesions of the carpal and tarsal bones.6,10,11 Symptomatic IOG cysts present with intermittent pain, occasional swelling and it This article describes an arthroscopic technique used for lunate intraosseous cyst resection associated with an autologous bone graft in a series of cases to prevent joint stiffness while respecting the scapholunate ligament (Fig 1, Fig 2, Fig 3).Our hypothesis was that arthroscopic treatment provides good results regarding cyst resorption with fewer complications.
