Arteriovenous Malformations Symptoms and Diagnosis

Symptoms of an arteriovenous malformation (AVM) usually appear in mid-life. Symptoms may include:

  • Headaches
  • Seizure
  • Difficulty speaking or finding words
  • Numbness or weakness on one side

The initial diagnosis of an AVM may be made using computed tomography or magnetic resonance angiography. NewYork-Presbyterian also employs catheter angiography, which provides three-dimensional images of blood flow in the brain. Catheter angiography provides important information about both the location and structure of the AVM and is an important diagnostic tool.
