[Conservative treatment of an aseptic abscess syndrome with splenic abscesses in Crohn's disease].

A 24-year old woman with a history of Crohn's disease developed bloody diarrhea and multiple abdominal abscesses, daily fever, leukocytosis, and elevated CRP several months after her immunosuppressive therapy with azathioprine was stopped. Recurrent abscess punctures did not detect any pathogenic germs and neither clinical nor serological response was achieved by administration of different antimicrobial therapies. Additionally, new splenic abscesses arose despite ongoing therapy.
