“…15,16 The narrower joint compartment and smaller synovial membrane area in the lower compartment of TMJ may be to blame for the low prevalence rate of SC there. 17 A clinical sign of tumourlike diseases, including diffuse synovial giant cell tumours, synovial cysts, and SC, is preauricular edema. 18 It is challenging to distinguish SC from TMD or osteoarthritis because of the other vague symptoms.…”

When cartilage-like tissue is present in the synovial membrane of joints, it is known as synovial chondromatosis (SC). The main cause is believed to be the metaplasia of embryonal mesenchymal tissue in the synovial membrane. The metaplastic foci grow within the joint space and can detach from the synovial wall, forming free-floating bodies. While SC is more commonly associated with trauma in the temporomandibular joint (TMJ), the exact relationship between trauma and SC remains unclear. Improved diagnostic techniques, such as CT and MRI, have led to increased recognition of SC in the TMJ. Gender differences in the prevalence of TMJ SC have been observed, with women being more affected. Diagnosis involves imaging techniques like X-rays, CT scans, MRIs, and surgical removal of loose bodies is the preferred treatment. Arthroscopy is recommended for small, isolated loose bodies, while open surgery may be necessary for complete removal. Long-term follow-up is essential to monitor for recurrence. Histopathological findings reveal a mixture of cartilage and bone, with ossification and calcification present.

“…18,19 The low prevalence rate of SC in the lower compartment of the TMJ might be due to the more narrow joint compartment and smaller area of the synovial membrane. 20,21 Preauricular swelling is a clinical symptom of tumor-like conditions such as diffuse tenosynovial giant cell tumor, synovial cysts, and SC. 22,23 Other nonspecific symptoms make it difficult to distinguish SC from TMD or osteoarthritis.…”

Temporomandibular joint synovial chondromatosis: An analysis of 7 cases and literature review

Objective: To investigate the diagnosis and treatment procedure of synovial chondromatosis (SC) of the temporomandibular joint (TMJ). Methods: Clinical features, imaging features, surgical methods, and prognosis of 7 patients with SC of the TMJ were analyzed. We also reviewed and analyzed surgery-relevant literature included in the Pubmed database in the past decade using the search terms “synovial chondromatosis” and “temporomandibular joint”, and found 181 cases. Results: There was no specific difference in the symptoms of SC in the TMJ in different Milgram’s stages in our cases and the cases mentioned in the literature. The main symptoms of SC in the TMJ were pain (100%, 7/7; 64.64%, 117/181), limited mouth opening (57.14%, 4/7; 53.59%, 97/181), swelling (14.29%, 1/7; 28.18%, 51/181), crepitus (28.57%, 2/7; 19.34%, 35/181), and clicking (14.29%, 1/7; 9.94%, 18/181) in our cases and cases from literature separately. The imaging features of SC were occupying lesions (including loose bodies or masses) (71.42%, 5/7; 37.57%, 68/181), bone change in condyle or glenoid fossa (1/7, 14.29%; 34.81%, 63/181), effusion (42.86%, 3/7; 20.99%, 38/181), joint space changes (42.86%, 3/7; 11.05%, 20/181) in our cases and cases from literature separately. The surgical procedures seem to depend mainly on the involved structures and the extension of the lesion rather than the Milgram’s stage. Conclusions: The clinical features of SC in the TMJ are nonspecific and easy to be misdiagnosed. MRI is helpful in the diagnosis of SC in the TMJ. The surgical procedures mainly depend on the involved structures and the extension of the lesion.

“…[44] Radiologic features of synovial chondromatosis include joint effusion, abnormal synovial thickening and enhancement suggestive of synovitis, adjacent bone erosion due to mechanical pressure, and calcified or noncalcified intra-articular loose bodies [Figure 8]. [41,42] In chronic disease, there may be imaging features of coexistent secondary osteoarthritis and asymmetric joint space narrowing. ere is potential for intracranial tumor extension due to its close proximity to skull base.…”

“…Synovial chondromatosis is a benign but locally aggressive disease characterized by chondroid metaplasia of the synovium, with subsequent formation of intra-articular loose bodies, causing destruction of the joint. [ 41 , 42 ] In the head and neck, it frequently involves the temporomandibular joint. Synovial chondromatosis can be divided into two subtypes – primary and secondary.…”

“…Synovial chondromatosis can be divided into two subtypes – primary and secondary. [ 4 1 , 42 ] Pathogenesis of primary form remains unknown, but according to recent cytogenetic studies, it is believed to be a benign neoplastic process rather than metaplastic disease. [ 43 ] In contrast, secondary form is associated with underlying joint diseases such as mechanical joint abnormalities or arthritic conditions.…”

There is a wide spectrum of head and neck cartilaginous lesions which include both neoplastic and nonneoplastic processes. Cartilaginous tumors of the head and neck are uncommon, posing a diagnostic challenge. Benign cartilaginous tumors that may occur in the head and neck include chondroma, chondroblastoma, chondromyxoid fibroma, osteochondroma, and synovial chondromatosis. Chondromesenchymal hamartoma is a rare non-neoplastic cartilaginous lesion that is included for the 1first time in the new WHO classification and radiologically can mimic a tumor. Malignant cartilaginous tumors include chondrosarcoma and chondroid variant of chordoma. Characteristic tumor locations, internal chondroid matrix calcification, and typical T2 hyperintense signal secondary to high-water content within the extracellular matrix of the hyaline cartilage are useful imaging features that narrow the differential diagnosis and help in diagnosing these diseases. This article presents a narrative review of the anatomy of the head and neck cartilaginous structures, discusses the current knowledge and imaging spectrum of benign and malignant cartilaginous tumors and tumor-like lesions of the head and neck.
