Fig 2. A 55-year-old man with ischemic colitis (patient 6). A, Axial T2-weighted (TR/ TE = 5000/110) images demonstrate bilateral symmetric hyperintense lesions in the dorsal medulla, vestibular, abducens, and focal tegmental lesions of the superior olivary nuclei of the dorsal pons, dentate nuclei of the cerebellum, the tectum of the midbrain, and the splenium of the corpus callosum. B, DWI (TR/TE = 4000/73) and ADC maps show mild hyperintensity and slightly high ADC of the dentate nuclei and obvious hyperintensity and very low ADC of the splenium of the corpus callosum. C, Follow-up MR images obtained 15 days after drug discontinuation. T2-weighted images show that the hyperintense lesions of the dentate nucleus and pons have disappeared, but a residual hyperintense lesion is seen in the splenium of corpus callosum. Note the near normalization of ADC and residual hyperintensity of the residual splenium lesion on DWI.
