[Primary duodenal carcinoma. Clinico-radiologic study]

Primary carcinoma of the duodenum represents about 0.35% of all gastrointestinal carcinomas and is thus a rare disease. The radiological diagnosis of a duodenal origin is made more difficult by the close proximity of the pancreas, biliary system, right kidney and transverse colon. Histologically, duodenal malignant tumours are usually adenocarcinomas. Between 1973 and 1983, eight patients with primary duodenal carcinomas were diagnosed at the University of Tübingen. Average age of the patients was 67 years. There was no sex difference. Average survival was 3.3 years.
