Third ventricular cavernous malformation: an unusual lesion

Abstract

Cavernomas constitute 5–10% of all the vascular malformations of the CNS. They commonly present during the 2nd and 5th decades of life. Intraventricular cavernomas constitute rare pathological entity, constituting 2.5–10.8% of cerebral cavernomas. The natural history of intraventricular cavernomas remains undefined to some extent. Those in third ventricle are different in biological nature and need more aggressive therapy. These cavernomas appear to have the ability to grow very rapidly, resulting in significant morbidity. It is not known whether waiting after acute hemorrhage from an intraventricular cavernoma improves our ability to remove the lesion safely or if waiting unnecessarily increases the risk of hydrocephalus, additional bleeding, or further lesion growth.
