关节内原发性软组织肉瘤极为罕见。本病例报告描述了一个关节内滑膜肉瘤的踝关节。一位51岁男性主诉右脚踝肿胀和进行性疼痛。踝关节侧位片显示距骨前部和后部的溶解性侵犯。计算机断层扫描成像显示一个低密度病变与钙化周围踝关节。磁共振成像显示弥漫性病变在T1加权像上呈等信号，在T2加权像上呈低到高信号。最终诊断为滑膜肉瘤。由于肉瘤扩散至整个踝关节，无法挽救足部;因此，患者接受了膝下截肢术，并接受了新辅助和辅助化疗。他死于致命的心律失常2年后，初步诊断。虽然关节内原发性软组织肉瘤极为罕见，但恶性肿瘤的可能性仍需考虑。
Intra-articular primary soft tissue sarcomas arc extremely rare. The present case report describes a case of intra-articular synovial sarcoma of the ankle joint. A 51-year-old man presented with complaints of swelling and progressive pain in the right ankle. Lateral radiographs of the ankle revealed lytic invasion of the anterior and posterior parts of the talus. Computed tomography imaging revealed a low-density lesion with calcifications around the ankle joint. Magnetic resonance imaging revealed that the diffuse lesion was isointense on T1-weighted images and hypointense to hyperintense on T2-weighted images. The final diagnosis was synovial sarcoma. The foot could not be salvaged as the sarcoma was diffusely spread throughout the ankle joint; thus, the patient underwent below-the-knee amputation with neoadjuvant and adjuvant chemotherapy. He succumbed from fatal arrhythmia 2 years following the initial diagnosis. Although intra-articular primary soft tissue sarcomas are extremely rare, the possibility of malignancy should be considered.
