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.
几个月来，一名14岁女孩颅内压升高，尽管第四脑室有广泛钙化，但一直未被识别。手术中发现一个李子大小的肿瘤在第四脑室内自由移动。它硬如骨头，必须完整摘除。组织学检查显示为高度钙化的内皮瘤型脑膜瘤。康复过程无并发症。一名12岁男孩第三脑室内有肿瘤，已存在7年，未接受手术。对内皮瘤型脑膜瘤进行了部分切除，无并发症。儿童期的脑膜瘤罕见，通常位于脑室内。它们起源于脉络丛的蛛网膜细胞。
