A 45‐year‐old‐woman was presented with fever, microangiopathic hemolytic anemia, thrombocytopenia, purpura, and mental status changes. She was diagnosed as having thrombotic thrombocytopenic purpura (TPP). She was treated with daily plasma exchange and antiplatelet drugs, steroids, and vincristine. This patient had a remarkable course with 18 days of coma on full therapy followed by essentially complete recovery coincident with an increase of the plasma exchange dose to two plasma volumes processed per procedure. The patient has remained well with discontinuation of plasma exchange. We conclude that prolonged coma without evidence of major central nervous system structural lesions in TTP should be treated vigorously and continuously with plasma exchange.
