Diagnosis: When a patient is first diagnosed with a cerebrovascular malformation, many questions arise. The malformation may be diagnosed after a hemorrhage or as a result of a seizure or possibly as a result of headaches. With improved techniques used to visualize the brain with newer radiographic studies, the diagnosis of an asymptomatic or minimally symptomatic lesion is increasing. Regardless of how the diagnosis is made, once it is decided that a vascular malformation is present, the next step is to ascertain the exact type of vascular malformation, which influences heavily the need for treatment and the exact details of potential treatment. There are typically four distinct types of vascular malformations which may occur throughout the central nervous system
Glossary: Arteriography , Angiography , cerebral angiography, arteriogram. A test to visualize the blood vessels in the head. This is an invasive procedure which requires that a catheter be inserted, usually in the groin or directly into the neck vessels, and threaded into the base of the skull. The dye material is then injected which shows up on x-ray, and rapid succession x-rays are taken to get a picture of the blood vessels in the head as they fill and empty with the dye material. MRI: Magnetic resonance imaging : A technique where a large magnet is used to visualize the contents of the cranium including the brain and blood vessels. This technique is noninvasive with the exception of an intravenous catheter which might be needed to give a contrast agent to better see brain lesions.
