title: Thoracic extraosseous, epidural, cavernous hemangioma: Case report and review of literature.
abstract: A 40-year-old male presented with mid-thoracic backache and progressive, ascending, spastic, paraparesis for one year. Magnetic resonance imaging demonstrated an extraosseous, extradural mass, without any bone invasion at the T2-T4 vertebral levels, located dorsal to the thecal sac. The spinal cord was compressed ventrally. The lesion was totally excised after a T2-T4 laminectomy. Histopathological examination revealed a cavernous hemangioma. The authors reported this case and reviewed the literature, to explain why extraosseous, extradural, cavernous hemangiomas should be considered in the differential diagnosis of extradural thoracic compressive myelopathy.
