A 65 year-old woman was admitted to our hospital for 4 year history of lower back pain and anterior band-like abdominal pain. Imaging studies, based on plain X-ray, Computed Tomography(CT) and Magnetic Resonance Image(MRI) scan revealed thoracic mobile schwannoma. Mobile intraspinal tumor such as schwannoma or ependymoma in film terminale is relatively more reported at cauda equina than thoracic area. Up to our knowledge, there has been only two reports of this mobile schwannoma in the midthoracic spine and the cervicothoracic junction. We report a case of thoracic mobile schwannoma, with review of surgical, pathological, radiological findings of this tumor.
