Rheumatoid Meningitis Occurring during Etanercept Treatment

Figure 2

Brain MRI findings on the 4th admission. (a) Axial T2 fluid-attenuated inversion recovery (FLAIR) image (1.5 T; TR 10000 ms, TE 108 ms). (b) Diffusion-weighted image (DWI) (1.5 T; TR 5000 ms, TE 75 ms). (c) T1-weighted image (T1WI) enhanced by gadolinium (1.5 T; TR 7.50 ms, TE 2.82 ms). MRI shows extensive thick linear hyperintensity of the leptomeninges in bilateral frontal lobe and the left parietal lobe on T2 FLAIR and DWI (red arrows). T1WI after gadolinium administration shows enhancement of the leptomeninges (red arrowhead).
