title: Cervical intradural extramedullary cavernoma presenting with isolated intramedullary hemorrhage.
abstract: Among cavernomas of the central nervous system, spinal ones are rare. The true incidence of spinal cavernomas is unclear, but with widespread use of magnetic resonance imaging the number of cases is increasing. Furthermore, cavernomas represent only 5-12% of all vascular anomalies of the spinal cord, with a mere 3% reported to be intradural and intramedullary in location. Cervical spine intradural extramedullary cavernomas are very seldom seen, and only 4 cases have been reported in world literature previously. In this report, a unique case of an intradural extramedullary spinal cavernoma was surgically treated in a patient who presented only with an intramedullary hemorrhage.
