title: Spinal cavernous angioma: a rare cause of subarachnoid hemorrhage.
abstract: A case of cervical intrathecal extramedullary cavernous angioma is presented. The rarity of this lesion in comparison with the more frequent vertebral cavernous angiomas with secondary extension to the epidural space is emphasized. The special features of this case are noted: the acute clinical onset due to recurrent subarachnoid hemorrhages, the visualization only by means of magnetic resonance imaging, and the unusual cervical level. The most debated characteristics of these lesions and the relevant literature are summarized.
