Intracranial venous malformations are abnormally enlarged veins in your brain. These enlargements aren't likely to cause symptoms or affect how the veins work.

Intracranial venous malformations might remain undetected or be found incidentally when you have a brain-imaging test for another condition.

Most often, this condition doesn't require treatment.
