FIGURE 2. Example of diffuse gastric localization on SRS in patient with ZES without MEN-1 or gastric carcinoid. Coronal view (A) and sagittal view (B) of SRS show diffuse uptake in stomach. This patient had ZES of 15 y duration. Upper gastrointestinal endoscopic findings were unremarkable except for hypertrophic gastric folds. Histopathology of 2 random Jumbo Cup biopsy (Pauldrach) samples from greater curvature showed linear and diffuse hyperplasia of gastric ECL cells. Mean fasting serum gastrin level was 250 pg/mL (normal level is <200 pg/mL).
