Abstract
Benign metastasizing leiomyomas (BMLs) are benign disseminated extrauterine tumors in patients with prior history of uterine leiomyomas and may occur years after hysterectomy. In this case, we presented 18 F-FDG and 68 Ga-FAPI PET/CT findings in a 37-year-old woman with benign leiomyoma metastasizing to lung and pelvis. The metastatic lesions demonstrated faint 18 F-FDG but elevated 68 Ga-FAPI activity, indicating the low level of glucose metabolism but excessive accumulation of activated fibroblasts in the BMLs. This case demonstrated that 68 Ga-FAPI PET/CT may be potentially useful in the evaluation of BMLs.
