Core Tip

Core Tip: Tuberculosis is a major threat to human health, and its incidence continues to rise, especially in developing countries. The gastrointestinal form of tuberculosis, however, is rare. We report here the case of an elderly male, whose primary duodenal tuberculosis was misdiagnosed as tumor. Despite the imaging diagnosis of malignant tumor, tissue biopsy did not support that diagnosis. After a series of additional tests, the patient was treated with anti-tuberculosis drugs for a period of 6 mo. Follow-up showed no new disease progression and no other complications. This case emphasizes the importance of differential diagnosis of duodenal space-occupying disease.
