What is a venous angioma in the brain?

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.

How serious is venous angioma?

Generally, these developmental venous anomalies do not require any treatment as they are part and parcel of the brains normal blood circulation, and any surgical excision or closure would result in complications. As they aren’t dangerous, long-term follow-up or imaging isn’t necessary either.

What does venous angioma cause?

An angioma rarely causes symptoms such as bleeding, seizure, hemifacial spasm, trigeminal neuralgia, aqueduct compression, nonhemorrhagic infarction and thrombosis of the draining vein. Even if it should bleed, the lesion can be managed conservatively in asymptomatic or mildly symptomatic patients.

Is venous angioma a tumor?

A developmental venous anomaly (DVA) is an unusual or irregular arrangement of small veins that may look like the spokes of a wheel. The veins drain into a larger central vein. DVAs are benign (not cancerous). DVAs also may be called venous angiomas or benign variations in venous drainage.

How is venous angioma treated?

Surgical excision involves removing the abnormal veins and the tissue around them. We use this approach most often with facial VM, to restore a more normal facial contour. Usually, we perform surgery after sclerotherapy, which helps to reduce bleeding and makes it easier to remove the VM.

Can a venous angioma cause headaches?

First, as one might expect, vascular headaches are a common type of pain, though the venous angioma can cause headaches in a variety of ways. The lesion may leak small amounts of blood, irritating the meninges and producing considerable pain.

Can a venous angioma cause dizziness?

DVAs also called venous angiomas are often asymptomatic and therefore are often found incidentally. The most frequent signs include headache, dizziness, seizure, and focal neurological deficits [3]. Before the advent of CT and MRI, DVAs were believed to be a rare cause of intracranial hemorrhage and seizures.

Can venous angiomas cause severe headaches?
