Meningiomas in children: MR and histopathologic findings.

Abstract

Meningiomas in children have a higher incidence of posterior fossa location and different histologic types than seen in adults. MR showed the tumors in our patients to be extra-axial, hyperintense on proton density- and T2-weighted images with intense enhancement on postcontrast T1-weighted images. Chromosomal aberrations were noted in two patients.
