MRI brain (A) Axial DWI and (D) GRE sequence showed insignificant findings; (B) axial T2WI showed bright signal axial (arrow); (C) FLAIR image showed an edematous swollen temporal lobe (arrow); (E,F) Contrast-enhanced images demonstrated a fine linear enhancement of cerebral falx and bilateral choroid (arrow). DWI, diffusion-weighted imaging; FLAIR, fluid-attenuated inversion-recovery; GRE (gradient echo); T2WI, T2 weighted image.

Brain magnetic resonance imaging (MRI) revealed right temporal lobe lesions (shown in Figure 1) and he was given treatment with gabapentin for his headache. The gadolinium enhanced brain MRI demonstrated a fine linear enhancement of the bilateral frontal sulcus, cerebral falx, bilateral choroid, and bilateral ventricular ependyma (shown in Figure 1).
MRI brain (A) Axial DWI and (B) axial T2WI showed a high signal and the size of the edematous area showed a marked increase at the right temporal occipital lobe (arrow); (C) FLAIR image showed a swollen, edematous temporal occipital lobe (arrow); (D) axial GRE sequence at the same level with the high signal of T2WI; (E,F) A contrast-enhanced image demonstrated an abnormal enhancement of the right temporal occipital lobe and bilateral choroid (arrow). DWI, diffusion-weighted imaging; FLAIR, fluid-attenuated inversion-recovery; GRE, gradient echo image; T2WI, T2 weighted image.

A brain MRI DWI image and T2-W image demonstrated an abnormal signal in the right temporal occipital lobe, which showed an increase in the range of the lesion (shown in Figure 2). A contrast-enhanced coronal T1-W image demonstrated obvious abnormal enhancement in the right temporal occipital lobe and bilateral choroid (shown in Figure 2).
