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.
大脑侧脑室脑膜瘤是罕见肿瘤，在所有颅内脑膜瘤中发病率约为0.5 - 4.5%。本文报告4例起源于三角区的脑室内脑膜瘤。第1例在X线平片上可见钙化肿块。第2例和第3例进行了CT和血管造影检查。第4例中，MRI和MRA被证明非常有用。肿瘤通过顶叶后部的经皮质入路切除。文中还讨论了关于脑室内脑膜瘤的现有文献。
