Synovial chondromatosis is a rare, benign condition that usually affects the larger diarthroidal joints of the axial skeleton. Approximately 120 cases of synovial chondromatosis involving the temporomandibular joint (TMJ) have been reported. People with this condition may present with swelling, pain, intracapsular sounds and limitation of mandibular movement. Because it is important to differentiate synovial chondromatosis from other joint pathologies, a thorough history and appreciation of clinical features of these conditions are necessary. Radiographs are an important component of the diagnostic armamentarium for discerning conditions that mimic synovial chondromatosis. A case of synovial chondromatosis diagnosed radiographically with the aid of volumetric computed tomography is described, followed by a discussion of potential causative factors and management strategies. A brief review of the differential diagnosis of synovial chondromatosis involving the TMJ is also provided.
滑膜软骨瘤病是一种罕见的良性疾病，通常累及中轴骨骼的大型滑膜关节。据报道，约有120例累及颞下颌关节（TMJ）的滑膜软骨瘤病病例。患有这种疾病的人可能会出现肿胀、疼痛、关节内弹响以及下颌运动受限。由于将滑膜软骨瘤病与其他关节病变区分开来很重要，因此全面了解这些疾病的病史和临床特征很有必要。X线片是鉴别类似滑膜软骨瘤病的疾病的诊断工具中的重要组成部分。本文描述了一例借助容积计算机断层扫描在影像学上诊断为滑膜软骨瘤病的病例，随后讨论了潜在的致病因素和治疗策略。还简要回顾了累及颞下颌关节的滑膜软骨瘤病的鉴别诊断。
