Intracranial venous malformations are abnormally enlarged veins in your brain. Find out more about diagnosis and treatment of this neurological condition.
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.
Because you may not have symptoms with intracranial venous malformations, your health care provider might find that you have the condition during testing for other neurological problems.
You might have these imaging tests to diagnose other neurological conditions:
Doctors usually don't treat intracranial venous malformations because they rarely cause symptoms. If you have unrelated symptoms, such as headaches, your doctor might prescribe medications.
Rarely, people who have intracranial venous malformations have seizures or bleeding in the brain (brain hemorrhage). These are usually caused by other vascular malformations that can be found with a venous malformation. Doctors typically treat seizures with medications.
Some hemorrhages require surgery, but many hemorrhages can be treated with medical management and observation in a hospital.
