Figure 1.

Magnetic resonance imaging (MRI) of the brain showed no abnormal signs. The two sides of the brain were symmetric, the gray matter and white matter were clearly demarcated, and there was no obvious abnormal signal shadow on T1WI, T2WI, FLAIR, and DWI axial view. (A-C) T1WI, T2WI, and T2-FLAIR axial view presenting medial temporal lobe; (D-E) T1WI, T2WI, and T2-FLAIR axial view presenting lateral ventricle. T1WI, T1-weighted imaging; T2WI, T2-weighted imaging; T2-FLAIR, T2-weighted fluid attenuated inversion recovery.
