Alliance to Cure Cavernous Malformation (formerly Angioma Alliance)

Cycle 2

Cavernous angioma, cavernoma, and cerebral cavernous malformation (CCM) are synonyms for mulberry-shaped abnormal blood vessels with thin, leaky walls. Cavernous malformations are commonly found in the brain or spinal cord. The most common first symptom is seizure, followed by hemorrhage and neurological deficits like blurred vision and weakness in limbs.
