Key Points

  • To investigate the uptake of 68Ga-DOTA-IBA in a rare case of sclerosing epithelioid fibrosarcoma and associated bone metastases.
  • Conducted 68Ga-DOTA-IBA PET/CT imaging in a case of sclerosing epithelioid fibrosarcoma.
  • Monitored uptake levels in both primary tumor and bone metastases.
  • Increased uptake of 68Ga-DOTA-IBA identified in bone metastases.
  • Unexpectedly, similar increased uptake was found in the primary tumor located in the abdomen.

Abstract

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.
