Synovial osteochondromatosis is a rare arthropathy of the temporomandibular joint. We report the computed tomographic findings in two subjects with this disorder. Both patients had increased soft-tissue density in the joint with multiple small calcified densities, many of which displayed peripheral calcification. Extensive erosions of the surrounding bony structures were present, affecting the condylar process and fossa, and, in one instance, the walls of the external auditory and carotid canals were thinned. We believe that computed tomography is superior to conventional imaging techniques and is useful in the depiction of disease and surgical planning in patients with temporomandibular joint synovial osteochondromatosis.
滑膜骨软骨瘤病是一种罕见的颞下颌关节病。我们报告了两名患有这种疾病的患者的计算机断层扫描结果。两名患者的关节软组织密度均增加，伴有多个小钙化灶，其中许多显示周边钙化。周围骨结构存在广泛侵蚀，累及髁突和关节窝，在其中一例中，外耳道和颈动脉管的壁变薄。我们认为计算机断层扫描优于传统成像技术，有助于颞下颌关节滑膜骨软骨瘤病患者的疾病描述和手术规划。
