title: Metastatic female adnexal tumor of possible wolffian origin (FATWO) of the appendix demonstrated by FDG PET/CT: the first reported case.
abstract: Both female adnexal tumor of possible wolffian origin (FATWO) and metastasis to the appendix from any primary tumor are extremely rare entities. The appendiceal metastasis from FATWO has not been reported, and there is a lack of the literature regarding FDG PET/CT study in both. We reported the case of an appendiceal metastasis from FATWO, demonstrated by F-18 FDG PET/CT. The case highlights the significance of FDG uptake in the appendix. When interpreting FDG PET/CT, caution should be exercised to identify uptake in the appendix, because it is easily misinterpreted as bowel activity.
