Hi, Thanks for writing in. The brain gets its inflow blood supply from arteries. These arteries then branch out in to capillaries and supply blood to the entire brain. The oxygen in blood is replaced by carbondioxide when the blood flows through these capillaries. Then the capillaries join to form veins which are an outflow channel of blood. You seem to be having an abnormal development of vein s in the frontal portion of your brain. This can give rise to many neurological symptoms like headache and seizures. Treatment depends on the location and size of the problem area and even non surgical interventional radiology treatment can help.
