Isolated fourth ventricle haemorrhage: “think beyond intracranial source’’ unusual presentation of lumbosacral spine arteriovenous malformation presentation

Abstract

Spinal arteriovenous malformations (SAVMs) are rare vascular lesions and account for about 4% of primary intraspinal masses. Since SAVMs can involve any location along the spinal column and produce a host of different problems, the symptoms are extremely variable. There are few reports of simultaneous cerebral SAH and intraventricular hemorrhage (IVH) following rupture of a spinal AVM (SAVMs). Herein, we present a rare case of Lumbo Sacral spine arteriovenous malformation, which clinically manifests as sudden onset of severe headache and vomiting due to isolated fourth ventricle Hemorrhage (IVH) without cerebral subarachnoid hemorrhage.
