Vascular malformations of the brain are mainly examined in four groups. These :

Since cavernoma and arteriovenous malformations are discussed in detail in another section, venous angioma and capillary telangiectasias will be discussed in this section.
Venous Angiomas
It is known as venous (vein) anomaly or venous malformation. A tuft of veins joins the central network, which drains into an enlarged superficial or deep venous system. Between the vessels is brain tissue. It can be seen very rarely in angiography examination. It is not hereditary. It is low flow and low pressure. Most of them are clinically asymptomatic, very rarely they can cause seizures and more rarely bleeding.
Treatment
In general, they are not treated because they allow drainage of contaminated blood from the surrounding tissue. Surgery is performed only in cases of proven bleeding or unavoidable seizures proven to be due to angiomas.
Capillary telangiectasia
They are the least understood vascular malformations. It consists of slightly enlarged low-flow capillaries. It may not be demonstrated in any radiological study. They are generally detected in autopsy studies without clinical significance. They contain neural tissue in them. It is usually single, may be more than one in familial syndromes. They do not require treatment.
