Abstract

We report a rare case of spindle cell rhabdomyosarcoma. Sarcomas generally exhibit an abnormal increased FDG uptake on ¹⁸F-FDG PET/CT imaging, while spindle cell rhabdosarcomas exhibits a significantly increased lesion uptake on ⁶⁸Ga FAPI PET/CT imaging compared to ¹⁸F-FDG. This case suggests that ⁶⁸Ga-FAPI PET/CT has potential value in evaluating spindle cell rhabdomyosarcoma.

Keywords: 18F-FDG; 68Ga-FAPI; PET/CT; spindle cell rhabdomyosarcoma.
