Three patients with perihilar cholangiocarcinoma. Reproduced from Li et al. [33]. A The hilar tumors on the CT scan also showed an increase in glucose metabolism on the PET scan. B CT analysis revealed that a lymph node along the head of the pancreas was enlarged. PET analysis showed that this region had high glucose metabolism. C CT analysis revealed a small nodule near the right abdominal wall with no obvious malignant features. However, PET/CT analysis showed that the nodule was a peritoneal metastasis, which was further verified by histopathology after surgical excision
