Detection of a second malignancy in prostate cancer patients by using [18F]Choline PET/CT: a case series

The role of radiolabeled choline (Cho) in patients with biochemical recurrence after radical treatment for prostate cancer (PCa) is well established. Its widespread clinical use has prompted the depiction of incidentalomas, unusual sites of metastatic lesions, as well as false positive and negative cases. We reported a series of patients affected by biochemical recurrence of PCa imaged by [18F]Cho positron emission tomography/computed tomography (PET/CT) which resulted suspected for a second malignancy
