Abstract：
:In order to study the clinical characteristics of intraventricular meningiomas, we analyzed retrospectively 25 patients and reviewed the literature with regard to incidence, clinical manifestation, imaging features, preoperative diagnosis, surgical findings, and histopathological results. Intraventricular meningiomas are quite rare, but they represent an important differential diagnosis of intraventricular neoplasms. Computed tomography or magnetic resonance imaging enable a correct diagnosis of intraventricular meningiomas in most of the cases. The tumors often grow slowly to a substantial size before they become symptomatic. The operative route should be selected according to the tumor's location. Out of the 24 lateral ventricular meningiomas in our series, 20 were resected via a posterior parieto-occipital transcortical approach, two were resected via a transcallosal approach, and another two tumors, located in the frontal horn and body of the lateral ventricle, were resected via a frontal approach. A median suboccipital craniotomy was performed for the fourth ventricular meningioma. The parieto-occipital route for lateral ventricular meningiomas is a safe surgical approach, which is not necessarily associated with postoperative visual deficits. Piecemeal removal of the tumor can be safely and easily performed and special attention should be paid to the choroidal vessels intraoperatively.
