Spontaneous splenic rupture complicating acute Q fever.
Q fever is usually a self-limited febrile illness that involves the lungs and the liver. Acute complications are rare. We present the case of a 30-yr-old patient with spontaneous splenic rupture during the course of acute Q fever infection. He was admitted to the hospital with high temperature and the radiological signs of an atypical pneumonia. Forty-eight hours after admission, he developed shock. Because of free intraabdominal liquid, a laparatomy was performed that revealed a tear in the enlarged spleen. A splenectomy was performed. The diagnosis of Q fever was established by a significant titer increase in complement fixation test and IgM-ELISA. Serological investigations into the patient's surroundings revealed evidence of Q fever infection in 10 additional persons. Q fever should be taken into account as a possible differential diagnosis in patients with unexplained febrile illness and symptoms of pneumonia. The acute course of Q fever infection can be complicated by splenic rupture. The diagnosis of an acute infection with Coxiella burnetii often requires serologic testing of a second serum sample obtained at least 10 days after the onset of symptoms. Q fever should be ruled out in cases of unexplained splenic rupture particularly in Q fever endemic areas.
