Diffuse subarachnoid and intraventricular hemorrhage as the presenting sign of a conus medullaris arteriovenous malformation: Case report

Abstract

Spinal arteriovenous malformations (AVMs) are rare vascular lesions that usually present with progressive myelopathy or less frequently, with acute neurological deficit due to hematomyelia or spinal subarachnoid hemorrhage (SAH). There are few reports of concomitant cerebral SAH and intraventricular hemorrhage (IVH) following rupture of a spinal AVM. Herein, we present a rare case of conus medullaris arteriovenous malformation, out-breaking with loss of consciousness due to SAH and IVH.

Keywords: Conus medullaris; Intraventricular hemorrhage; Spinal arteriovenous malformation; Subarachnoid hemorrhage.
