Brucellosis: differential diagnosis of acute abdominal pain.

A 34-year-old Turkish woman presented with septic fever, sweats, arthralgia, and abdominal pain. Further examination revealed generalized lymphadenopathy, hepatosplenomegaly, pancytopenia, and multiple caseous granulomas. Microbiological diagnosis revealed Brucella melitensis type 3 as causative agent. This case report demonstrates that abdominal pain can be a symptom in brucellosis, and caseous granulomas may occur. In our mobile society Brucella infection should be considered as possible differential diagnosis in patients with fever, lymphadenopathy, hepatosplenomegaly, and pancytopenia, although human brucellosis is rare in Germany and other Western countries.
