Liver abscess complicating Crohn's disease presenting as thoracic empyema. Case report and review of the literature.

A 28-year-old man with a history of Crohn's disease presented with right pleuritic pain and dyspnea. Chest radiography showed a right pleural effusion. Thoracocentesis yielded purulent fluid that subsequently grew Enterobacter aerogenes. Computed axial tomography of the abdomen revealed right subphrenic abscess and right hepatic lobe abscess. Antibiotic therapy and surgical drainage resulted in complete recovery. A review of the English literature produced 18 cases of liver abscess complicating Crohn's disease. Details of 14 of these cases are summarized.
