Figure 3 (A-D): Posterior fossa glioma. Contrast-enhanced axial (A) and sagittal (C) MRI images show a conglomerate ring-enhancing lesion (arrow) that was mistaken for a tuberculoma. Axial fused FDG PET/CT image (B) shows low-grade FDG uptake (arrow). Axial fused 11C methionine PET/CT image (D) shows uptake (arrow), consistent with a high-grade malignancy. Note normal uptake in the pituitary gland
