Colloid cysts of the third ventricle

Abstract
Since computerized tomography scanning became available at the Division of Neurosurgery in July, 1979, 13 patients have undergone removal of colloid cysts of the third ventricle by transfrontal or transcallosal routes. Computerized tomography has increased the number of colloid cysts detected in the foramen of Monro during neurological diagnostic workups. The clinical and diagnostic aspects and changing concepts in the treatment of colloid cysts are reviewed.
