SUB-ARACHINOID HEMORRHAGE AND ONSETTING M ARGINAL HEMODISEROSIS CAUSED BY A CAVERNOMA OF THE SPINAL-CORD

An intradural cavernoma of the spinal cord located at T12 was identifi ed in a 39-year-old man presenting with recurrent episodes of lower ba ck pain on the basis of MRI findings. The patient was hospitalized for severe subarachnoid hemorrhage complicated with hydrocephalia requiri ng ventriculo-peritoneal draining. Marginal asymptomatic hemosiderosis of the spinal cord above the malformation was observed. The cavernoma which did not involve nervous tissue was removed surgically to avoid the risk of recurrent bleding and further development of marginal hemo siderosis.
