  Fig. 1 Fluid-attenuated inversion recovery images (A), (B), and (C) show hyperintense cerebrospinal fluid (CSF) on right temporal area (arrowhead) and a high signal intensity lesion on left medial temporal area suspicious of limbic encephalitis (B) (arrow). Positron emission tomography-computed tomography images (D) and (E) show an asymmetric increase of fluorodeoxyglucose uptake in the left medial temporal area matching the high signal intensity lesion seen in the image (B, arrow). Gradient recalled echo T2-weighted image (F) shows magnetic susceptibility artifact matching hyperintense CSF, seen in fluid-attenuated inversion recovery image (C, yellow curved line).
