Abstract

Gallbladder's adenocarcinoma with enteroblastic differentiation (GAED) is extremely rare. A 43-year-old woman complained of pain in the right upper abdomen, and enhanced CT showed a cystic and solid mixed mass in the hepatic hilar region. Adenocarcinoma with enteroblastic differentiation was pathologically identified. 18 F-FDG PET/CT revealed a lesion in the gallbladder neck with increased FDG uptake, accompanied by a cystic and solid mixed mass in the hepatic hilar region with liver and lymph node metastases. Gallbladder biopsy was also carried out, and GAED was confirmed. 18 F-FDG PET/CT may assist in the evaluation of GAED and guide biopsy.
