title: Meningiomas of the lateral ventricles of the brain.
abstract: Meningiomas of the lateral ventricles of the brain are rare tumours with an approximate incidence of 0.5-4.5% among all intracranial meningiomas. Four cases of intraventricular meningioma arising from the trigone are presented. In 1-st case the calcified mass was visible on straight radiographs. In 2-nd and 3-rd cases CT and angiography was performed. In 4-th case MRI and MRA proved to be very useful. The tumours were removed by transcortical approach in the posterior parietal area. The available literature on intraventricular meningiomas has been discussed.
