Multiple Primary Tumors as Shown by 18F Fluorodeoxyglucose and 68Ga Trivehexin Positron Emission Tomography-Computed Tomography in a Single Case

Key Points

To identify multiple primary tumors through advanced imaging techniques in a single patient case.
Conducted an 18F fluorodeoxyglucose PET-CT examination in a 73-year-old man diagnosed with bladder carcinoma.
Utilized 68Ga Trivehexin PET-CT for further evaluation of suspicious lesions.
Histopathological analysis confirmed multiple tumors including lung and rectum adenocarcinomas.
Identified lung adenocarcinoma, rectum adenocarcinoma, and a ring cell tumor of the stomach.
Imaging findings correlated with histopathological results, confirming multiple primary tumors.

Abstract

Seventy-three-year-old man with previous diagnosis of bladder carcinoma with suspicious pulmonary nodule and rectum polypoid lesion in a follow-up 18F fluorodeoxyglucose PET-CT examination. The histopathology results revealed lung adenocarcinoma as well as rectum adenocarcinoma and ring cell tumor of the stomach, which was additionally determined by the 68Ga Trivehegzin PET-CT imaging.
