“…Cases of synovial chondromatosis limited to the popliteal bursa have been reported 10–12. However, bursal synovial chondromatosis differs from the present case, as the cartilaginous or osteocartilaginous bodies would be multiple and smaller.…”

“…However, bursal synovial chondromatosis differs from the present case, as the cartilaginous or osteocartilaginous bodies would be multiple and smaller. Also, to establish a diagnosis of bursal synovial chondromatosis, it must be demonstrated that the cartilaginous or osteocartilaginous bodies had their origin in the bursal wall by cartilaginous metaplasia of the synovial connective tissue 310–12. In our case, the osteochondral body was lying loose inside the popliteal cyst; MRI was very helpful in evaluating the lesion, as a single discrete mass seemingly separate from the cyst wall was clearly visible.…”

Popliteal cysts, although commonly seen, are rarely associated with motion restriction or calcification. Radiological features are of soft-tissue swelling, with occasional reports of calcifications or small osteochondral bodies inside the cysts. We report a giant osteochondral body in a popliteal cyst, with significant mechanical block to flexion. This type of mass has to be differentiated from synovial osteochondromatosis, calcifications in the cyst, extraosseous and intraarticular osteochondromas. Complete excision of the cyst resulted in complete recovery of range of motion.

“…They may be migrated from the joint through the communication channel, 22 or they may arise by synovial osteochondromatosis in the cyst, which is an indirect complication of Baker cysts. 29 The benign metaplasia of the cells in the synovial membrane enables them to produce cartilage nodules on the inner surface of the synovial membrane (chondromatosis). When the nodules are broken off, the free cartilage nodules may undergo calcification or ossification (osteochondromatosis).…”

“…They are usually multiple and in small, even size. 29 Loose bodies in Baker cysts may be osseous, chondral, or osteochondral fragments. They may be the result of fragmentation of the joint surface or osteoarthritis, fracture of the osteophytes, or synovial osteochondromatosis in the joint or in Baker cysts.…”

Baker cysts are the most common pathologic finding in the sonography of the popliteal fossa. They have a wide range of sonographic appearances. Some of them may need to be recognized and differentiated from other popliteal lesions. Therefore, familiarity with their different imaging appearances is useful for clinical practice. This review summarized different presentations of Baker cysts. They are described in several categories, organized according to their shape and formation: typical Baker cysts and their mild variations, atypical small Baker cysts, ʎ-shaped Baker cysts and their related variations, Baker cysts with extension into nearby muscles, and Baker cysts with complications. The related differentiations are included in each category. The pathogenesis of Baker cysts is also discussed.

Introduction: The osteochondromatosis is a rare synovial tissue metaplasia. The location at the shoulder is very rare. Bursal affection is exceptional.Case presentation: We report a case of a male, 41 years old living in north Morocco and presenting to the rheumatology outpatient clinic at Fes Hassan II University Hospital with a swelling of the right shoulder that had been evolving for two years, without any history of trauma, gradually increasing in size, without fever or alteration of the general state. Clinical examination revealed a 5 cm soft, nontender oval mass on the anterior surface of the right shoulder with no signs of inflammation but limited range of motion. Plain X-ray was normal and diagnostic ultrasonography revealed an avascular multilocular cystic mass. A differential diagnosis was considered and other conditions with comparable pictures were ruled out. The diagnosis was confirmed by a magnetic resonance imaging showing synovitis and distension of the sub acromiodeltoid bursa with many rounded bodies, few millimeters in size of intermediate signal in T1 and T2 without enhancement after intravenous gadolinium. A diagnosis of osteochondromatosis of the subacromiodeltoid bursa (third stage) was made. The patient underwent an open bursectomy and histological examination further verified the diagnosis.Conclusion: Presenting such rare cases could help in raising the awareness of rheumatologists regarding such conditions when considering a differential diagnosis for patients presenting with monoarticluar shoulder swelling. Excision of the tumor has a remarkably better prognosis.
