Abstract

Choroid plexus papillomas are only infrequently located in the third ventricle. Two infants with such lesions are presented and the diagnosis by computed tomography described. The transcallosal approach to the third ventricle was employed in both cases and led to successful excision. This approach is recommended for lesions in the anterior third ventricle in children, and the occurrence of subdural effusions as a complication is pointed out.
