Abstract
The number of newly registered tuberculosis in 1997 increased compared to the previous year, making it the first rise in the last 38 years. We describe here one case of tuberculosis that occurred with mediastinal and abdominal abscess. A 65-year-old male visited our hospital with a swelling at the midline of his abdomen. CT revealed an encapsulated mass tracking from the anterior mediastinum to the abdomen. An incision was performed for diagnosis and treatment. The mass was found to be an abscess and its contents were of positive acid-fast bacilli by bacterial examination. Antituberculous therapy was initiated postoperatively.
