FDG PET/CT Findings in Malignant Intraductal Papillary Mucinous Neoplasm of the Bile Ducts

Abstract

A 58-year-old man with no significant symptoms was referred to the hospital due to the presence of an intrahepatic cystic tumor and a dilated intrahepatic bile duct. F-18 FDG PET/CT demonstrated intense FDG uptake in the marginal region of the cystic tumor. Subsequently, the patient underwent a right hemihepatectomy with extrahepatic bile duct resection. The histopathology revealed a malignant intraductal papillary mucinous neoplasm of the bile ducts with dysplasia. This report thus documents the FDG PET findings in malignant intraductal papillary mucinous neoplasm of the bile ducts, which showed an intense FDG uptake in the tumor.
