Imaging findings of right-sided trigone intraventricular meningioma: A case report

Abstract

Intraventricular meningioma is a case with an incidence about 0.5%-2% of all cases of meningioma. About 80% of all intraventricular meningiomas occur in the trigone of lateral ventricle and more common on the left side. In this case, we present a 43-year-old woman with Right-sided Trigone Intraventricular Meningioma. The diagnosis and assessment of intraventricular meningiomas remains a challenge. Radiological examination has a major role in cases of intraventricular meningioma. Presurgical diagnostic imaging may be useful in corroborating the diagnosis. In this article, we describe the patients with intraventricular meningiomas in CT and MR imaging that revealed useful data for diagnosis.
