Case in brief

A 68-year-old woman with a history of colon cancer had a right breast nodule detected incidentally on routine contrast-enhanced CT, where it showed moderate enhancement. Subsequent [18F]AlF-NOTA-FAPI-04 PET/CT demonstrated intense focal uptake (SUVmax: 6.63). Histologic examination identified the lesion as a benign phyllodes tumor.

What made this case unusual

The benign breast tumor showed intense focal FAPI uptake, illustrating that this imaging finding is not specific to malignancy.

Diagnostic / clinical pearl

In a cancer survivor, an FAPI-avid lesion may be benign; histologic confirmation can help prevent unnecessary treatment.
