⁶⁸Ga-PSMA PET/CT in Hepatic Metastasis From Pancreatic Neuroendocrine Tumor

A 53-year-old man underwent both F-18-FDG and Ga-68-PSMA PET/CT to evaluate a mass in the left upper abdomen. The scans demonstrated intense uptake of both F-18-FDG and Ga-68-PSMA in the mass. However, a nodule in the left lobe of the liver showed increased uptake of Ga-68-PSMA, which was not FDG avid. Histopathological examination after surgical resection of the mass confirmed the diagnosis of pancreatic neuroendocrine tumor (G2). Subsequently, Ga-68-DOTATATE PET/CT demonstrated intense radioactivity of the nodule in the left lobe of the liver consistent with hepatic metastasis from neuroendocrine tumor.
