In the surveillance of recurrent biliary cancer, several diagnostic imaging modalities are currently used. Usually CT is the most common method for surveillance of postoperative patients, but MRI and PET/CT scans are also widely used. Recurrent biliary cancer can manifest as local recurrence, liver metastasis, lymph node metastasis, and peritoneal metastasis. Imaging findings of a locally recurrent tumor or metastatic lymph node enlargement overlaps with benign postoperative changes, thus radiologists commonly overlook subtle CT findings or misinterpret them as benign postoperative changes.
