A case of an epidural granuloma due to Schistosoma mansoni compressing the spinal cord at T7-T9 is presented. The patient, a 35-year-old Brazilian man, started complaining of recurrent back pain since 2003. A magnetic resonance imaging (MRI) scan showed a large epidural mass extending from T7 to T9 and causing mild spinal cord compression. Through a bilateral laminectomy the bilharzioma was subtotally removed without significant bleeding. The histopathology confirmed the diagnosis of granuloma due to S. mansoni. The patient recovered completely. Although the MRI is nonspecific, this differential diagnosis should be included in homogeneous epidural lesions without bone involvement, more than ever in endemic countries or during the evaluation of travelers to those regions.
本文报告一例因曼氏血吸虫引起的硬膜外肉芽肿压迫胸7至胸9脊髓的病例。患者为一名35岁的巴西男性，自2003年起开始反复出现背痛。磁共振成像（MRI）扫描显示一个巨大的硬膜外肿块，从胸7延伸至胸9，导致轻度脊髓压迫。通过双侧椎板切除术，血吸虫瘤被大部分切除，且无明显出血。组织病理学证实为曼氏血吸虫引起的肉芽肿。患者完全康复。尽管MRI表现不具特异性，但对于无骨质受累的均匀硬膜外病变，尤其是在流行地区或对前往这些地区的旅行者进行评估时，应考虑这一鉴别诊断。
