Abstract

A 31-year-old male presented with severe back pain and paraparesis. Imaging studies demonstrated an extraosseous, extradural mass without bone invasion at the T11-T12 vertebral level, located dorsal to the thecal sac. The spinal cord was compressed ventrally. The lesion was completely excised after a T11-T12 laminectomy. Histopathological examination revealed a cavernous hemangioma. The patient's symptoms improved after excision of the lesion.
