Cavernous Malformations and Angiomas
Cerebral cavernous malformations (CCMs), also referred to as cavernous angiomas or cavernous hemangiomas, are blood vessels that formed abnormally. As opposed to other kinds of hemangiomas, CCM vessels develop and create problems in the brain or spinal cord. These malformations have the appearance of a small mulberry and can vary in size from 2 millimeters to several centimeters in diameter. They may be hereditary but most often occur on their own.
CCMs may leak blood, leading to bleeding in the brain or spinal cord (hemorrhage). Brain or spinal hemorrhages can generate a wide range of more apparent neurological symptoms, depending on the location of the CCM in the nervous system.
