Magnetic resonance imaging (MRI) showed a nonenhancing lesion with high signal intensity on T2-weighted images and low signal intensity on T1-weighted images of the left mesial temporal lobe [Figure 1a-d].
Post-operative MRI. (a and b) T1-weighted image without and with gadolinium. (c) T2-weighted image, (d) T2-FLAIR, (e) Diffusion-weighted imaging

A postoperative MRI scan within 72 hours depicted a small area with an increased T2 signal intensity with no abnormal diffusion restrictions, suspicious for residual tumor [Figure 2a-e].
Histology staining. (a) Hematoxylin and eosin, x100. (b) Glial fibrillary acidic protein (GFAP), x100. (c) Ki-67 (mib1), x100. (d) Neuronal nuclei (NeuN), x100
