Late onset seizures, hemiparesis and blindness in hemolytic uremic syndrome.

Author information

Children's Medical Center of Dallas, USA.


Neurologic complications of hemolytic uremic syndrome, including seizures, usually occur early during the acute phase of the illness. We report a3-year-old girl with classic diarrhea-associated hemolytic uremic syndrome who developed late onset seizures, hemiparesis and transient blindness on the 17th hospital day, at which time her recovery was characterized by improvement in her blood pressure, serum electrolytes, renal function, hematocrit and platelet count. A CT and MR revealed brainstem and posterior parietal and occipital infarct/edema. The association of these radiologic findings within the posterior distribution along with visual loss and seizures are unique to posterior reversible encephalopathy syndrome. Within 7 days, she regained motor function and vision and had no further seizure activity. At 6 months follow-up, physical examination revealed normal motor function and vision and a repeat MR showed near resolution of the previous findings with minimal occipital lobe gliosis. This case report describes the uncommon finding of late onset seizures occurring during the recovery phase of hemolytic uremic syndrome with MR findings consistent with posterior reversible encephalopathy syndrome.
