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.
