Fourth ventricular meningioma in an adult: Case report and review of the literature

Abstract

Abstract Meningiomas are one of the most common clinical entities in everyday neurosurgical practice. Most meningiomas are extra-axial dural-based lesions. They typically occur along intradural venous sinuses, at the confluences of multiple cranial sutures and also others sites where arachnoid granulations and arachnoid cell rests occur. Most of these tumors also do occur within the lateral ventricles than third ventricle but they are exceptional in fourth ventricle thought to arise from the choroid plexus without dural attachment. Here we present two cases of fourth ventricle meningiomas.
