PRIMARY MALIGNANT NEOPLASMS OF THE DUODENUM: DISCUSSION BASED ON SEVENTEEN CASES, WITH EMPHASIS ON RADIOLOGIC DIAGNOSIS

• Only radiologic diagnosis can provide early enough recognition of tumors involving the duodenum to allow resection of the lesion. While the radiologist must be particularly alert to the less common lesions of the alimentary tract, he must be equally aware of the factors that could obscure the lesions during the examination. Of 17 duodenal lesions seen at the Ochsner Clinic, 14 were diagnosed as adenocarcinomas and 3 as sarcomas. After such a lesion is suspected, either because of specific clinical manifestations, depending on the location of the tumor in the duodenum, or because of x-ray findings, both clinical findings and radiologic findings should be able to complement each other. The treatment of choice is surgical excision.
