[The radiological diagnosis of the Zollinger-Ellison syndrome (author's transl)].

: The article discusses the y-ray diagnosis of the Zollinger-Ellison syndrome, including 13 with multiple endocrine adenomatosis, Type I. This syndrome is governed by complex pathophysiological processes determining the x-ray symptoms. Besides the predisposition to ulcers, which will persist despite partial gastrectomy, changes at the duodenum (hypertrophy of Brunner's glands) and proximal jejunum (bulging of folds) are relatively typical. However, the final diagnosis of the Zollinger-Ellison syndrome is a clinical one. The syndrome is caused by non-beta islet cell tumors of the pancreas, associated with hypergastrinemia. Since these tumors are often multiple and small, angiography is not very rewarding. It is frequently impossible to distinguish the benign from the malignant tumors on the grounds of histological findings, the only criterion being their biological behaviour, if the exclusion or identification of metastases.
