    Abstract:
    Acute acalculous cholecystitis is a very rare clinical presentation of Q fever. We report the case of a 38-year-old man who presented with fever associated with elevation of liver enzyme levels and thickening of the gallbladder wall on abdominal ultrasonography and who was initially diagnosed with acute acalculous cholecystitis. Due to the persistence of fever and transaminase elevation despite antibiotic treatment, a liver biopsy was performed. Characteristic "doughnut" epithelioid granulomas were observed, suggesting a diagnosis of granulomatous hepatitis caused by Q fever, which was confirmed by serological methods. Treatment with doxycycline was commenced and the patient subsequently showed rapid clinical improvement, with disappearance of fever and normalization of liver enzyme levels. We review 8 cases of acute cholecystitis associated with Q fever published in the literature and stress the importance of liver biopsy in the etiological diagnosis of patients with prolonged fever and abnormal liver function tests.
