Abstract

A 57-year-old woman with a history of right breast cancer surgery 22 years prior presented with CT findings of gastric and intestinal wall thickening, accompanied by mild-to-moderate FDG uptake on 18F-FDG PET/CT. Pathological results showed lobular breast cancer metastasis. The lesions showed significantly higher uptake on 18FAl-NOTA-FAPI PET/CT, and an additional sternal metastasis was identified.
