Indium-111 pentetreotide uptake by pancreatic polypeptide cell hyperplasia: potential pitfall in somatostatin receptor scintigraphy.

AbstractA 71-year-old man with duodenal gastrin cell tumor was being evaluated for residual/metastatic disease. Somatostatin receptor scintigraphy (SRS) identified a 2-cm area of focal uptake within the head of the pancreas, consistent with a pancreatic neuroendocrine tumor. Pathological examination
