Cavernoma

The precise cause of cavernomas is not known with certainty. A minority of people living with them develop symptoms but they can be a source of significant disability.

Cavernomas located in the cerebral hemispheres. These are early a cause of brain haemorrhage and can be a cause of seizures.

Cavernoma located in the deeper centres of the brain and the brain stem are more likely to produce symptoms or disability.

Relatively rare and poorly understood spinal cord cavernomas can be a source of significant disability.
