Cerebral vascular malformations cause many health problems, the most common of which is rupture of a blood vessel leading to a stroke due to cerebral hemorrhage or causing pressure on the brain leading to epilepsy and convulsions.

Transient headaches are often ignored, but few people understand that they can be a warning sign of cerebral vascular malformation, which if treated late can be life-threatening.

Computed tomography (CT) is a diagnostic imaging technique. This technique is a machine system that emits many X-rays to scan an area of the body in cross-section, combined with computer processing to produce 2-dimensional or 3-dimensional images of the part being scanned.
