title: [Thoracic extramedullary subdural and epidural of inflammatory myofibroblastoma: a case report].
abstract: 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 aggressive. The exact pathogenesis is still unknown. Tumor resection is the first choice to treat. Long-term follow-up with MRI is required for the patient.
