title: Paraganglioneuroma of the duodenum. Report of a case with radiographic findings, angiographic findings and a review of the literature.
abstract: A 59-year old Cuban male had seven episodes of gastrointestinal bleeding. Angiographic and radiographic studies revealed a polypoid mass in the second portion of the duodenum. The mass proved to be paraganglioneuroma. A review of the literature reveals only 25 previously recorded such cases. Eighty-eight per cent of the lesions were located in the second part of the duodenum: 84% of the patients were symptomatic. The two main symptoms noted were abdominal discomfort (45.5%) and bleeding (47.6%). None of the lesions was a malignant or functional tumor.
