Abstract
A patient with left upper quadrant breast cancer who had 18 F-FDG PET/CT imaging underwent 68 Ga-Trivehexin PET/CT. 68 Ga-Trivehexin PET/CT showed higher radiotracer accumulation in the primary tumor, left internal mammary lymph nodes, and axillary lymph nodes compared with 18 F-FDG PET/CT. However, Trivehexin uptake was not observed in FDG-positive lymph nodes in the mediastinum and left hilar region. Benign cytological findings were noted in the biopsy of the subcarinal lymph node. This case demonstrates that the use of 68 Ga-Trivehexin PET/CT in suspicious lymph nodes in areas difficult to biopsy in breast cancer cases can contribute to accurate staging.
