摘　　要：本文报道1例胸椎椎管内占位患者，根据术前影像学检查误认为硬脊膜外黄韧带肥厚，切除硬脊膜外病灶后患者症状无改善，且出现双下肢肌力减弱，再行手术探查发现硬脊膜下存在占位，术后组织病理检查结果为髓外硬脊膜下和硬脊膜外炎性肌纤维母细胞瘤（inflammatorymyofibroblastictumor，IMT）。由于IMT发生在椎管内罕见，目前全世界仅有10余例报道，现将本病例报道如下。We present here a rare case of thoracic extramedullary subdural and epidural of leisions. The initial diagnosis of preoperation was hypertrophy of ligamentum flavum, however, after excision of the epidural lesions, the symptoms got worse. A second operation found the subdural leisions which were then totally resected. Two pathological examinations confirmed it was inflammatory myofibroblastic tumor （IMT）. The incidence of this disease is extremely low. IMT is benign in histology, but it can be aggres- sive. The exact pathogenesis is still unknown. Tumor resection is the first choice to treat. Long-term fol- low-up with MRI is required for the patient.
