Elevated 68Ga-FAPI Activity in Leiomyosarcoma

Abstract

Leiomyosarcoma is an aggressive subtype of soft tissue sarcoma with frequent metastatic relapse after curative surgery. Herein, we report the 68Ga-FAPI PET/CT findings in a 45-year-old woman with leiomyosarcoma. 68Ga-FAPI-04 PET/CT detected increased FAPI uptake in abdominal leiomyosarcoma and liver metastases. The positive findings of 68Ga-FAPI in this case highlighted that 68Ga-FAPI may have potential value in the evaluation of leiomyosarcoma.
