Sclerosing epithelioid fibrosarcoma is extremely rare and aggressive soft-tissue sarcoma. Here, we report the 68 Ga-DOTA-IBA PET/CT findings in a case with sclerosing epithelioid fibrosarcoma with bone metastases. 68 Ga-DOTA-IBA PET/CT revealed increased uptake of DOTA-IBA in bone metastases. Unexpectedly, 68 Ga-DOTA-IBA uptake was also observed in the primary sclerosing epithelioid fibrosarcoma in the abdomen.
Liu et al. (2026) studied this question.
