Synovial sarcoma is a type of soft tissue sarcoma that commonly occurs around large joints. However, primary intra-articular synovial sarcoma is considered an extremely rare variant of synovial sarcoma. We present a case of synovial sarcoma arising from the hip joint in a 17-year-old female patient. Clinical, radiographic, magnetic resonance imaging and histopathology findings are described. The patient underwent neoadjuvant chemoradiation therapy followed by right hemipelvectomy, and there was no local recurrence in the subsequent follow ups. Unfortunately, the patient had pleural metastasis, and she was treated with palliative chemotherapy. To the best of our knowledge, there is only one published case report in the English literature on intra-articular synovial sarcoma from the hip joint.
滑膜肉瘤是一种常见于大关节周围的软组织肉瘤。然而，原发性关节内滑膜肉瘤被认为是滑膜肉瘤的一种极其罕见的变异类型。我们报告一例17岁女性患者发生于髋关节的滑膜肉瘤病例。描述了其临床、影像学、磁共振成像及组织病理学表现。该患者接受了新辅助放化疗，随后行右半骨盆切除术，在后续随访中未出现局部复发。不幸的是，患者出现了胸膜转移，接受了姑息性化疗。据我们所知，英文文献中仅有一篇关于髋关节关节内滑膜肉瘤的病例报告。
