Intramedullary lumbar lesion mimicking spinal cord tumor: a case of non-neoplastic intramedullary spinal cord lesion.

Non-neoplastic intramedullary spinal lesion cases are rarely seen in the literature. We would like to present this case for differential diagnosis of intramedullary spinal tumors. The aim of this case report is to attract attention on the MRI findings with lack of contrast enhancement and long syrinx formation which differs these types of lesions from the intramedullary spinal tumors. Intraoperative, pathological and immunohistochemical findings of non-neoplastic intramedullary spinal lesion were discussed.
