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”
