Splenic infarction has been associated with haematologic and tromboembolic disorders and, more rarely, with infectious diseases. A case of splenic infartion during an attack of brucellosis is reported. Symptoms included persistent left upper quadrant pain and fever. An abdomen scan confirmed the presence of a triangular area of hypodensity in the spleen. Serum and culture exams confirmed the diagnosis of brucellosis. The patient recovered once a course of antibiotic therapy was completed, after 2 and half months.
