A case of empyema with subphrenic abscess

Abstract

A 75-year-old female was admitted to our hospital with complaints of fever, cough and left hypochondralgia. She had been operated for cholecystectomy ten years ago. Chest roentgenogram indicated bilateral pleural effusion. Tube drainage was done to the left thorax and empyema was caused by Bacteroides fragilis and Escherichia coli (E. coli). Though antibiotic therapy was already being conducted, the left hypochondralgia persisted. A CT scan and MRI demonstrated local subphrenic abscess around the spleen due to E. coli. Tube drainage was conducted to the subphrenic abscess under ultrasound control and and the symptoms disappeared rapidly. The present results show that examination of the abdomen is necessary for empyema with complication of compromised host. The past history of abdominal surgery and disturbance in the biliary tract should also be considered.
