FET-CREB fusion-positive intracranial mesenchymal tumor is a newly recognized provisional tumor type. Usefulness of FDG PET/CT in the management of this tumor is rarely reported. We describe FDG PET/CT findings in a case of FET-CREB fusion-positive intracranial mesenchymal tumor with metachronous extracranial metastases to the mediastinum, mesentery, and left Leg. The metastatic tumors showed mild to moderate FDG uptake. This case indicates that FET-CREB fusion-positive intracranial mesenchymal tumors can develop extracranial metastasis, and FDG PET/CT may be useful for detecting extracranial metastasis of this rare tumor.
