However, contrast media can induce hemolytic anemia with a broad spectrum of hemolytic manifestations. We report a 38-year-old patient with very severe immune hemolytic anemia after the application of iomeprol due to a CT of the thorax/abdomen. In this case report, we illustrate the diagnostics and treatment of life-threatening hemolytic anemia induced by a contrast medium that was successfully treated with eculizumab.
