Hemolytic uremic syndrome with intracranial hemorrhage following mitomycin C administration

Abstract

A 50-year-old woman treated for breast cancer with mitomycin C developed severe hypertension, followed by deep coma 3 days later. Computed tomography of the brain showed frontoparietal intracranial hemorrhage accompanied by subarachnoid hemorrhage. The patient was diagnosed additionally with hemolytic uremic syndrome (HUS) based on hemolytic anemia with schistocytosis, thrombocytopenia, and acute renal failure. The patient underwent hemodialysis and plasmapheresis with no improvement. We present the pathologic findings of the general vessels, which has been reported rarely. This case represents the first reported intracranial hemorrhage in HUS following mitomymycin C administration. We emphasize the need to control blood pressure in patients with HUS.
