Also referred to as cavernomas, cavernous angiomas, cavernous hmangiomas or intracranial vascular malformations, these are clusters of small, abnormal, blood vessels and large, thin-walled blood vessels filled with blood. Typically found in the brain, they do also occur in the spinal cord, the dura (the covering of the brain) and the nerves in the skull. They cover a broad range of sizes from as little as a quarter of an inch to 3 to 4 inches.
Treatment: Cavernomas can potentially haemorrhage, putting the patient at huge risk. So, they require surgical excision via a craniotomy.
