GONZALEZ, Celso et al. Síndrome de Zollinger Ellison secundario a gastrinoma duodenal: Reporte de un caso y revisión de la literatura. Gen [online]. 2010, vol.64, n.1, pp.46-49. ISSN 0016-3503.

Zollinger-Ellison syndrome is a disorder caused by a gastrin hypersecretory neuroendocrine tumor which produces severe gastric acidity. In 60% to 90% of the cases itÊs malignant; metastatic nodules are observed in 50% to 67% of the cases, and are located primarily in the so called Gastrinoma triangle. Theconventional imaging methods have poor sensibility in detecting these lesions, especially for those that are less than 1 cm. The endosonography conjointwith the Somatostatin receptors scintillography are the standard imaging goldmethods to diagnose these lesions. We report the case of a male 57 years-oldpatient who came to consult with acute pancreatitis, peptic ulcer disease anddiarrhea. By endosonography we detected and staged a single lesion. He received surgical treatment successfully
