[Choroid plexus papilloma of the third ventricle in infancy: a case report]

The incidence of choroid plexus papilloma is about 0.5% of all intracranial tumors, but they are only infrequently found in the third ventricle. This is a case report of choroid plexus papilloma of the third ventricle in an infant. A make child in his 7th month of age was admitted because of large head circumference, on the 28th February, 1989. CT scan demonstrated hydrocephalus caused by a tumor in the third ventricle. Total removal of the tumor was performed on the 8th of March. Histologically the tumor was found to be choroid plexus papilloma. The patient suffered from postoperative subdural effusion and convulsions, so we performed ventriculoperitoneal shunt on the 14th April, and convulsions were controlled by zonisamid.
