MR Spectroscopic Profile of an Angiocentric Glioma

A 2-year-old female with focal motor seizures was referred to our Center for brain MRI. Imaging revealed a non-enhancing, demarcated, cortically-based mass lesion in the right superior frontal gyrus and cingulate gyrus. Single voxel MR spectroscopy through the tumor showed markedly elevated myoinositol and/or glycine, mildly elevated choline, and moderately decreased N-acetyl aspartate. Histological assessment of the lesion following gross total resection was diagnostic of an angiocentric glioma. Herein, we present the first illustration of MR spectroscopic findings from a typical angiocentric glioma.
