Retroperitoneal synovial sarcoma is extremely rare, with only a few cases reported in the literature. The diagnosis is often made late, due to anatomical considerations, with common symptoms including low back pain and weight loss. Imaging is critical for diagnosis, often revealing a heterogenous mass with the "triple sign" and calcifications. The main differential diagnoses include liposarcoma, undifferentiated pleomorphic sarcoma and leiomyosarcoma. Surgical resection remains the treatment of choice, though it is not always feasible, which contributes to the poor prognosis. The presented case is a retroperitoneal synovial sarcoma in a 29 years old man with findings from ultrasound, computed tomography and magnetic resonance imaging.
腹膜后滑膜肉瘤极为罕见，文献中仅报道了少数病例。由于解剖学因素，诊断往往较晚，常见症状包括腰痛和体重减轻。影像学检查对诊断至关重要，常显示出具有“三联征”和钙化的异质性肿块。主要鉴别诊断包括脂肪肉瘤、未分化多形性肉瘤和平滑肌肉瘤。手术切除仍然是首选治疗方法，尽管并非总是可行，这导致了预后不良。本文介绍的病例是一名29岁男性的腹膜后滑膜肉瘤，伴有超声、计算机断层扫描和磁共振成像的检查结果。
