Spectral analysis of lesion metabolites. (1–3) N-Acetyl aspartate (NAA) and choline (Cho) were decreased and increased, respectively. The Cho + Cr/NAA ratio was 4.47, 3.20, and 2.79 in the corpus callosum, semi-oval centers, and the area below the frontal cortex, respectively. Lactic acid peaks were also increased in these regions. Positron emission tomography–computed tomography (PET–CT). 4 High metabolism was observed in the corpus callosum and both ventricles, suggesting the presence of a malignant glioma
