Abstract

Meningiomas are among the most common brain tumors in adults. They are most commonly located over the cerebral convexities and are infrequently found in an intraventricular location. Ionizing cranial radiation is a risk factor for late occurrence of meningiomas within the radiation field. While pathologic grading of meningiomas is straightforward, significant variability often exists between pathologists in applying standard grading criteria. This has implications for prognosis. Radiation-induced meningiomas may also have predilection to recur. The authors describe a case of an intraventricular meningioma occurring 23 years after cranial irradiation for childhood acute lymphoblastic leukemia.
