Abstract

We present 99m Tc-HYNIC-TOC SPECT/CT findings in a case of microcystic serous cystadenoma of the pancreatic head. The pancreatic tumor showed intense 99m Tc-HYNIC-TOC uptake mimicking neuroendocrine tumor on SPECT/CT. This case indicates that microcystic serous cystadenoma should be included in the differential diagnosis of 99m Tc-HYNIC-TOC-avid pancreatic masses.
