Overview

Intracranial venous malformations are veins in the brain that are unusually large. These larger veins aren't likely to cause symptoms or affect how the veins work.

Some people may have an intracranial venous malformation that is never diagnosed and never causes symptoms. Sometimes, they're found by accident when you have a brain imaging test for another condition.

Intracranial venous malformations usually don't require treatment.
