[A case of primary intestinal tuberculosis in which small intestine perforation developed].

We report herein on a case of the primary intestinal tuberculosis in which small intestine perforation developed. A 60-year-old man with congestive heart failure developed fever and sudden onset of abdominal pain while he was in the hospital. Computed tomography of the abdomen showed a large amount of free-air and the thickening of a part of the ileum. Perforation of the gastrointestinal tract was diagnosed, The patient underwent emergency exploratory laparotomy and a partial resection of the ileum was performed. The presence of nodules in the ileum suggested possible tuberculosis of the intestine. Pathologically caseating epithelioid granulomas were noted and the diagnosis of tuberculosis of the ileum was made although microbiologically tuberculous bacilli were not documented. The patient was successfully treated with antituberculosis chemotherapy. Although intestinal tuberculosis is a rare cause of intestinal perforation, it is important to include intestinal tuberculosis as one of the cases.
