Abstract
In patient with Zollinger-Ellison syndrome, it is difficult to localize gastrinoma because the tumor is frequently small and multiple. However, accurate localization of the tumor is important for the treatment Among various imaging modalities, somatostatin receptor scintigraphy (SRS) has been recognized to be the most sensitive tool for the detection of neuroendocrine tumors such as gastrinomas based on the presence of high-affinity binding sites for somatostatin. Recently, we experienced a case of Zollinger-Ellison syndrome caused by gastrinomas which was localized by SRS. This is the first case report of gastrinoma detected by SRS in Korea. SRS can facilitate tumor detection in patient with Zollinger-Ellison syndrome and should be considered as the first-line diagnostic method in the early course of the disease.
