Cavernous angioma
Cavernous angiomas are clusters of abnormal blood vessels found in the brain, spinal cord, and, rarely, in other areas of the body.A typical cavernous angioma looks somewhat like a raspberry, but it can range in size from microscopic to inches in diameter. It is made of multiple little bubbles (caverns) of various sizes, filled with blood and lined by a special layer of cells (endothelium). These cells are similar to those that line normal blood vessels, but the bubble-like structures of a cavernous angioma are leaky and lack the other layers of normal blood vessel wall. A cavernous angioma can cause seizures, stroke symptoms, hemorrhages, and headache.
