A HEALTHY 28-year-old Pakistani woman developed fever, malaise, and diffuse edema, rapidly progressing to multiple organ failure with encephalopathy, anuric renal failure, hemolytic anemia, and thrombocytopenia. The patient was diagnosed with thrombotic thrombocytopenic purpura (TTP) and treated with hemodialysis, intravenous corticosteroids, and plasma exchange with cryoprecipitate-poor plasma. After 2 weeks, her mental status improved, but she complained of bilateral vision loss.
