  Fig. 1. Brain magnetic resonance imaging (MRI). Brain MRI showed an ill-defined, mass-like lesion (arrow) with high signal intensities at right basal ganglia, insula, external capsule, the temporal lobe on fluid-attenuated inversion recovery (FLAIR) image (A) and irregular enhancement (arrow) on axial contrast-enhanced T1-weighted image (B). (C) MR spectroscopy showed the slightly increased value of choline to creatine ratio and decreased value of N-acetylaspartate peak at the mass-like lesion involving right basal ganglia, insula, external capsule, and temporal lobe, suggesting tumorous condition (red square: volume of interest). (D) In the postoperative follow-up MRI, FLAIR showed remained tumor (arrow) and postoperative hemorrhage (arrowhead) on the right temporal lobe. After 3 months with seizure presentation, diffusion-weighted image (E) and FLAIR (F) showed newly occurred, multifocal hyperintense lesions (arrowheads) at left temporoparietal lobes.
