A 67-year-old man with a history of left upper lobe resection of poorly differentiated adenocarcinoma 1 year ago underwent FDG PET/CT for restaging. The images demonstrated a round cystic lesion with peripheral FDG uptake and centrally photopenic region. Additional focus of increased activity was detected in the left lobe of the liver. The patient underwent the Whipple and partial hepatectomy. The surgical pathology demonstrated concurrently the metastasis to the pancreas from the lung adenocarcinoma and a primary moderately differentiated cholangiocarcinoma.
