title: [Two cases of intraventricular meningiomas in children (author's transl)].
abstract: For several months a 14-year-old girl had suffered from increased intracranial pressure which in spite of extensive calcification in the fourth ventricle had not been recognized. During the operation a plum-sized tumour was found free moving in the fourth ventricle. Being hard as bone it had to be extracted in toto. The histological examination showed a highly calcified endotheliomatous meningioma. Recovery without complications. For seven years a 12-year-old boy had a tumour in the third ventricle which has not been operated on. Partial removal of the endotheliomatous meningioma without complications. Meningiomas in childhood are rare and are usually intraventricular. They originate in the arachnoidal cells of the choroid plexus.
