A review of papillomas of the third ventricle. One case report.

The Authors present one case of choroid plexus papilloma localized in the third ventricle. This is in fact the only case in a series of about 4,000 patients operated on for brain tumors at the Neurosurgical Institute of the University of Rome. They consider 56 cases reported in the literature. Out of these, 43 are described and summarized in a table according to the clinical, radiological and surgical features. Twentyfive were the patients operated on, the average mortality in the cases which underwent indirect or not specified operation was 80%; that of patients submitted to a direct approach or to subtotal excision was 50%; and finally 3 patients out 13 (about 23%) who had total resection, died after surgery.
