Gallbladder Uptake Mimicking Liver Metastasis on Lu-177-DOTATATE Posttherapy Scan Gallbladder Uptake on Lu-177-DOTATATE Scan

Abstract

We represent the case of a 61-year-old man with atypical carcinoid tumor of the lung. On posttherapy Lu-177-DOTATATE whole-body scan, focal intense uptake in the inferomedial side of the liver was detected. Pretherapy Ga-68-DOTATATE PET/CT showed no sign of liver metastasis, and posttherapy diagnostic dynamic liver MRI is used to exclude metastatic liver disease. Focal intense uptake was attributed to physiological gallbladder uptake.
