Kolloidcyster i tredje hjerneventrikkel.

Abstract

Third ventricle colloid cysts are benign lesions that can result in obstructive hydrocephalus with accompanying headache and loss of consciousness. In rare cases, colloid cysts can cause sudden, unexpected death. Colloid cysts are most often discovered as an incidental finding on CT or MRI of the head, without the patient having clinical signs of hydrocephalus.
