Figure 1 (A) Chest radiograph anteroposterior view on day 1 showing patchy alveolar opacities in right middle, lower, and left upper zone with normal cardiac silhouette. (B) Follow-up chest radiograph after 7 days, showing complete resolution.

Figure 2 (A) Fluid-attenuated inversion recovery axial scan on day 1 shows mild hyperintensity, in the splenium of the corpus callosum. (B) On diffusion-weighted imaging, b1000 shows bright signal in the posterior limb of internal capsule, splenium of the corpus callosum, deep white matter, and (C) dark signals on the apparent diffusion coefficient map. On follow-up magnetic resonance imaging after 6 days, (D) fluid-attenuated inversion recovery axial scan shows hyperintensity in the splenium of the corpus callosum, genu, and posterior limb of internal capsule. (E) On diffusion-weighted imaging, b1000 shows mildly bright signals in the splenium of the corpus callosum, normal appearance in the posterior limb of the internal capsule and deep white matter. (F) The apparent diffusion coefficient map shows near normal appearance.
