Acute abdomen as atypical presentation of brucellosis: report of two cases and review of literature.

Abdominal involvement in brucellosis is seen in the acute, subacute and chronic disease. It is not typical, however, that acute abdomen is the presenting feature of brucellosis. In this paper, two cases of serologically diagnosed brucellosis are reported, both presenting initially with acute abdomen and fever. In brucella-endemic regions of the world, brucellosis has to be considered in the differential diagnosis of acute abdomen and fever. With definitive diagnosis, unnecessary laparotomy can be avoided.
