Definition of Cavernoma
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Cavernoma: also called cavernous angiomas or cavernous malformations, are clusters of abnormal blood vessels with small bubbles (caverns) filled with blood that resemble a raspberry. They vary in size from just a few millimeters to a few centimeters in diameter. Blood flow is weak in the cavernoma, and blood can leak out. Cavernomas typically occur in the brain and spinal cord, and can cause headaches, seizures, hemorrhages, and stroke. Cavernomas are not cancerous and will not spread to other parts of the body.
