Borderline ovarian tumors have a far more favorable clinical course compared to malignant ovarian tumors. To date, the role of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) for the differentiation of an ovarian mass remains controversial. Discrepancy between FDG-PET and magnetic resonance (MR) images is rare but may cause a serious dilemma in decision-making. We report a case of a borderline ovarian tumor showing discrepancy between MR and FDG-PET findings. FDG-PET findings may help with the differentiation of ovarian masses when clinical findings are not coincidental.
