A Case of Meigs' Syndrome: The (18)F-FDG PET/CT Findings

The findings of an ovarian mass with marked ascites and pleural effusion are highly suggestive of malignancy, especially in a postmenopausal female with an elevated level of CA-125. However, benign conditions such as Meigs' syndrome should be considered in the differential diagnosis if the primary mass shows benign features. (18)F-FDG is known to be useful to differentiate between malignant and benign diseases, and this utility is also promising in the case of ovarian tumor. We present here a case of Meigs' syndrome that was evaluated by (18)F-FDG PET/CT, and this helped the preoperative diagnosis be made. (18)F-FDG PET/CT is a promising modality to diagnose the pathological character of an ovarian tumor preoperatively, which can lead to a proper therapeutic plan.
