Non-neoplastic Vascular Malformations of the Brain 1. Arteriovenous Malformations (AVMs) 2. Venous Angioma 3. Cavernoma 4. Capillary Teleangiectasia 5. Direct Fistula ( McCormick-1966 )

Arteriovenous Malformations

Patophysiology

Clinical presentation 1. Hemorrhage - most common - 82% significant IP component - SAH, IVH 2. Seizures 3. Mass effect ( increased ICP ) 4. Progressive Neurologic Deficit 7% of patients with AVMs present associated aneurysms

Imaging studies  CT scan  CT angiography  MRI / angio - MRI  Cerebral angiography

Cavernomas = cavernous angioma, cavernous hemangioma

Clinical presentation  Seizures  Progressive Neurological Deficit  Hemorrhage ( usually IP ) > 50 % asymptomatic

Imaging Studies  CT  MRI - hemosiderine ring ( “salt and pepper” appearance )  Angiography – “angiographically occult”
