Synovial chondromatosis is an uncommon condition, and the involvement of the shoulder joint is rare. A 15 year old female patient presented to author's institution for right shoulder pain. We checked the plain radiographs and MRI. And they showed that a diagnosis of synovial chondromatosis in the shoulder, and they also demonstrated that the disease involved the bicipital tendon sheath as well as glenohumeral joint. We removed all loose bodies with total synovectomy by arthroscopic procedure, and a miniopen procedure for the lesions of biceps tendon sheath. Arthroscopic treatment affords excellent visualization of the shoulder joint with less morbidity. However, with current arthroscopic techniques, it is difficult to manage the synovial chondromatosis of biceps tendon in bicipital groove. The authors suggest that the complete elimination of synovial chondromatosis involving shoulder requires a mini-open procedure for the lesions of biceps tendon sheath in addition to the arthroscopic resection of the affected synovium and loose body removal in the glenohumeral joint.

Synovial chondromatosis (SC) in temporomandibular joint is a rare benign disorder characterized by cartilaginous metaplasia of the mesenchymal remnants of the synovial tissue. The etiology of the disease is unclear but may be associated with trauma, overuse, local infection, and embryologic disturbance. SC does not spontaneously resolve and respond to nonsurgical treatment. SC should be differentially diagnosed with other temporomandibular joint disorders such as arthralgia or osteoarthritis because surgery should be done for managing it. However, primary diagnosis of SC is not easy because of nonspecific symptoms and signs. For the patients with unsuccessful conservative treatment response, especially accompanied by crepitus, preauricular swelling or posterior open bite, computed tomography/cone-beam computed tomography or magnetic resonance imaging should to be performed to exclude SC. We discussed the importance of the early diagnosis and surgical treatment of SC from this case.

Purpose : We evaluated the results of the arthroscopic treatment of nine cases of synovial chondromatosis in the knee joints. Materials and Methods : From June 1989 to September 1999, eight patients nine cases with synovial chondromatosis involving knee joints underwent arthroscopic total synovectomy and removal of loose bodies. There were 6 females and 2 males. The average age at surgery was 44.1 years(range, 20-57 years). The average follow-up period was 5.9 years (range, 2.5-7.3 years). All cases had pain and swelling and two cases had locking preoperatively. Flexion contracture was found in three cases. Results : Pathologic finding revealed Milgram I in one case, Milgram II in six cases and Milgram III in two cases. There were six cases of generalized synovial hypertrophy and one case of localized type. All patients had symptomatic relief by arthroscopic total synovectomy and loose body removal. Second arthoroscopic surgery was performed in one patient due to recurred lesions 11 months after the primary surgery. Conclusion : Clinical results of the synovial chondromatosis with arthroscopic total synovectomy and loose body removal were satisfactory. Arthroscopic total synovectomy was also effective for the recurred case.

Melorheostosis is a rare disease, belonging to the sclerotic bone dysplasia group. Initially described by Leri and Joanny in 1922, its etiology remains unknown. Onset is usually insidious, with deformity of the extremity, pain, limb stiffness, and limitation of motion in the joints. The typical radiographic appearance consists of irregular hyperostotic changes of the cortex, resembling melted wax dripping down one side of a candle. Treatment is usually symptomatic and conservative; however, conservative treatment is unsatisfactory due to functional issues when involving the distal extremity. We report on two cases of melorheostosis with synovial chondromatosis of the foot treated by mass excision.

Synovial chondromatosis is a rare metaplastic disease affecting the joints, including the temporomandibular joint (TMJ). Since its symptoms are similar to those of temporomandibular disorders, a careful differential diagnosis is essential. A 50-year-old male patient was referred with the chief complaint of pain and radiopaque masses around the left TMJ on panoramic radiography. Clinically, pre-auricular swelling and resting pain was found, without limitation of mouth opening. On cone-beam computed tomographic images, multiple calcified nodules adjacent to the TMJ and bone proliferation with sclerosis at the articular fossa and eminence were found. T2-weighted magnetic resonance images showed multiple signal-void nodules with high signal effusion in the superior joint space and thickened cortical bone at the articular fossa and eminence. The calcified nodules were removed by surgical excision, but the hypertrophic articular fossa and eminence remained. A histopathological examination confirmed the diagnosis. The patient was followed up few months later without recurrence.

Temporomandibular joint cysts usually occur between the second and fourth decade of life. There is a female predominance to male of approximately 3 to 1. The patients complain of swelling, pain and sometimes decreased mouth opening. Synovial cysts of the temporomandibular joint seem to develop by an increase of intraarticular pressure due to trauma or inflammation which causes capsular herniation. However, if inflammatory synovial cysts develop by an increase of synovial fluid into inflammation tissue in the capsule without capsular herniation, a differential diagnosis should include synovial chondromatosis and synovitis. This is a case report of a synovial cyst developed in a capsule of the temporomandibular joint.

Synovial chondromatosis (SC) is a rare, benign disease found in metaplastic cartilaginous nodules within the synovial membrane. The etiology of SC is not well-known, but it may be associated with trauma, chronic abnormal loading, or inflammatory joint disease. It is often found in knee, elbow, ankle, and shoulder joint but rarely in the temporomandibular joint (TMJ) area. SC of TMJ frequently appears in middle age and more often in females. Clinical symptoms include periarticular swelling, pain, crepitus, and limitation of joint motion. The most common feature is a radiographic finding of loose bodies in the joint. Irregularity of joint space and condylar head is also observed. Treatment involves the surgical removal of synovium and loose bodies. The prognosis is good, with low postsurgical recurrence rate. Functional improvement of the joint and pain relief are noted in many patients. Malignant transformation of SC has not been recorded. In this study, we report a 54-year-old female patient who experienced discomfort on the right TMJ with SC on the area but made a satisfactory recovery after surgery.

Pigmented villonodular synovitis, synovial chondromatosis, long-standing rheumatoid arthritis, hemophilic arthropathy, chronic tophaceous gout, amyloid arthropathy, tuberculous arthritis, and hemangioma are the synovial diseases showing low signal intensity on T2-weighted image. Synovial deposition of hemosiderin, urate, and amyloid and fibrosis or caseous necrosis of hypertrophied synovium are known as the pathologic causes of T2 signal intensity. Because of the low incidence of the synovial lesions showing T2 low signal intensity, recognition of these diseases would be helpful for the exact diagnosis.
