On day 32, he suddenly developed a headache and visual disturbance and experienced three short convulsions, which were followed by postictal confusion and high fever. T2 and FLAIR MRI images of the brain revealed hyperintense signal alterations in bilateral subcortical regions of the temporoparietal and occipital lobes, consistent with posterior reversible encephalopathy syndrome. His mental status was fully recovered after 7 h of conservative treatment, including antihypertensive therapy. On hospital day 56, the renal function of the patient had recovered, and he was discharged without neurologic sequelae.
