Case in brief

A 73-year-old man with a history of bladder carcinoma underwent an 18F fluorodeoxyglucose PET-CT scan, which revealed a suspicious pulmonary nodule and a rectal polypoid lesion. Histopathological analysis confirmed the presence of lung adenocarcinoma, rectal adenocarcinoma, and a ring cell tumor of the stomach, further characterized by 68Ga Trivehexin PET-CT imaging.

Diagnostic / clinical pearl

This case highlights the importance of advanced imaging techniques, such as 68Ga Trivehexin PET-CT, in identifying multiple primary tumors in patients with a history of malignancy.
