What is Cavernous malformations?

12:39 - 3 November , 2023


These are abnormal blood vessels in the brain or spinal cord that have a reduced diameter and thin walls, which causes slow blood circulation that is susceptible to leaks and hemorrhages.

Cavernous malformations, whose origin is generally spontaneous, can also be hereditary. They usually look like a small raspberry that can measure from 0.5 to 10 centimeters. When they appear in the brain, they can produce symptoms similar to a stroke. In contrast, when they appear in the spinal cord, there may be numbness in the limbs, movement difficulties, and intestinal and bladder alterations.
