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
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”
