[Tuberculous stenosis of the duodenum].

A 51-year-old man came to hospital admission one year after the first occurrence of upper abdominal pain, nausea, fever, melaena and discrete symptoms of inflammatory disease, X-ray examination of the chest, colon and ileum were normal. Sonography and computertomographic examination showed a mass in the pancreatic head region. Diagnosis was established by endoscopy and examination of bioptic material, showing ulcerating and stenosing tuberculosis of the duodenum with caseating, tuberculoid granuloma and acid stabile bacilli. Tubercle bacilli of the human type could be demonstrated in bacterial culture. Granuloma of epitheloid cells could also be found in the liver. Drug therapy with tuberculostatic drugs brought about complete healing of the macroscopical lesions within 4 weeks. In patients with stenosing processes of the duodenum tuberculosis should also be taken into account as a rare cause of this condition.
