The Developmental Venous Anomaly (DVA) is a benign, venous malformation in the brain that in most cases remains symptom-free. Typically, the abnormality is characterized by a bunch of dilated, medullary veins that converge on a large-caliber central drainage vein. The veins are involved in the normal drainage of brain tissue, so an occlusion can lead to hemorrhagic infarction . Often, DVAs are discovered accidentally during magnetic resonance imaging of the brain. However, you can also deal with other vascular malformations such as B. cavernomas .
In the past, the term venous angioma was also used for this anomaly , but it is assumed to have a neoplastic origin and is therefore incorrect.
