Causes And Risk Factors For A Cavernous Malformation

A cavernous malformation is a condition where an individual develops abnormally shaped blood vessels that cause issues in the spinal cord and brain. The blood vessel malformations can range in diameter from two millimeters to several centimeters and have a shape that resembles a small mulberry. Symptoms of a cavernous malformation include severe headache, vomiting, speech difficulties, vision loss, balance difficulties, nausea, numbness on one side of the body, and double vision. Most cases of cavernous malformations are a single, idiopathic occurrence without the involvement of any genetic factors. However, around one-fifth of all individuals affected by cavernous malformations have an inherited or familial type of the disorder. When symptoms of a cavernous malformation emerge in an individual, MRI scans and genetic tests are performed to diagnose the disorder. Treatment for cerebral malformations is individualized and may include observation, medications, and surgery.
