Cavernous malformations are the abnormal blood vessels that appear like a small mulberry in the spinal cord or the brain. Usually, these are hereditary and occur on their own. Malformations often leak blood, causing bleeding inside the brain. This can lead to neurological symptoms that depend on the location of the malformation in the nervous system.
The symptoms of cavernous malformations are numbness or weakness in the face, arm or leg, vision loss, unsteadiness or double vision along with difficulties in swallowing or speaking. Seizures may also be experienced as a response to this condition. Some may also have to deal with repeat hemorrhages that can occur as soon as the first hemorrhage occurs or later.
Some people with CCM will never know they have the disorder because they will never experience symptoms. The prognosis for CCM is variable for each individual, since the location and number of lesions determine the severity of the disorder. CCM can be fatal if it causes severe brain hemorrhages.
