Fig 1. A 54-year-old man (patient 4) with spontaneous bacterial peritonitis. A, Axial FLAIR (TR/TE/TI = 6000/120/2000 ms) images demonstrate bilateral symmetric hyperintense lesions in the dorsal medulla (black thick arrows), vestibular (black thin arrows), abducens (white arrows), and a focal tegmental lesion of the superior olivary nuclei (arrowheads) of the dorsal pons, dentate nuclei of the cerebellum, red nuclei and tegmentum of the midbrain, and the splenium of the corpus callosum. B, DWIs (TR/TE = 3396/60) show bright signal intensity at the peripheral part of the cerebellar dentate nuclei and central part of the splenium. The lesions of the low pons and tegmentum of the midbrain are slightly hyperintense, and the lesions of dorsal medulla and central part of dentate nuclei are isointense on DWI. C, ADC maps show a focal area of low ADC in the splenium of the corpus callosum (black arrow) and a high ADC area in most areas of the dentate nuclei (white arrows).
