Cauda equina intradural extramedullary cavernous haemangioma: case report and review of the literature.

Cavernous haemangioma (cavernoma) is a benign vascular lesion, exceptionally located in cauda equina. We report a case, diagnosed and operated in the Department of Neurosurgery from Pitesti County Emergency Hospital, of a 60-year-old woman with history of lumbar region distress, who presented with low back pain, paravertebral muscle contracture, and bilateral lumbar radiculopathy, with sudden onset after lifting effort. The preoperative diagnosis was done using computed tomography (CT) and magnetic resonance imaging (MRI), and the patient underwent surgery-two level laminectomy, dural incision, and tumor dissection from the cauda equina nerve roots under operatory microscope. Histopathological examination confirmed the positive diagnosis of cavernoma of cauda equina. The patient's outcome was favorable, without postoperative neurological deficits.
