title: [A choroid plexus papilloma of the third ventricle in the neonatal period--a case report].
abstract: The incidence of choroid plexus papilloma is about 0.5% of all intracranial tumors, but choroid plexus papilloma in the third ventricle is rare. Fortuna reported 56 cases of choroid plexus papilloma of the third ventricle in 1979. Among them, the neoplasm of the third ventricle in the neonatal period was not found. This report is a case of choroid plexus papilloma of the third ventricle in the neonatal period. A 34 day-old female was admitted to our service with complaints of head enlargement, vomiting, and convulsive seizures on January 8, 1981. Enlarged head had been noticed by her family within the first two weeks. On admission, a marked congenital hydrocephalus was diagnosed by CT scan with symmetrical dilated ventricles and no abnormal high or low density area, and V-P shunt was performed on the next day. But several days later, she suffered from progressive abdominal distension, which was disclosed due to CSF overproduction by a choroid plexus papilloma. When the tumor was recognised by enhanced CT scan, her general condition was too poor to attempt a surgical procedure, and she died on March, 19, 1981. Histologically the neoplasm was a typical choroid plexus papilloma of the third ventricle. So far as we know, this case is the first one of the choroid plexus papilloma of the third ventricle in the neonatal period.
