Intraventricular meningiomas are rare and account for approximately 0.5 to 3% of all meningiomas and 9.8 to 14% of all intraventricular tumors. Most rarely, intraventricular meningomas occur in the third and fourth ventricles. The article reviews the literature devoted to meningiomas of a rare localization, in the fourth ventricle. On the basis of published surgical procedures and neuroimaging data, we divided posterior cranial fossa meningiomas into tumors completely located in the fourth ventricle cavity and those with a partial intraventricular component, which are not associated with any structures outside the ventricle. The reason for this study was our own clinical observation.
脑室内脑膜瘤较为罕见，约占所有脑膜瘤的0.5%至3%，占所有脑室内肿瘤的9.8%至14%。最罕见的情况是，脑室内脑膜瘤发生在第三和第四脑室。本文回顾了有关罕见部位（第四脑室）脑膜瘤的文献。基于已发表的手术方法和神经影像学数据，我们将后颅窝脑膜瘤分为完全位于第四脑室腔内的肿瘤以及具有部分脑室内成分且与脑室以外任何结构无关的肿瘤。进行这项研究的原因是我们自己的临床观察。
