A Case of Meigs' Syndrome: The 18F 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. 18F 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 18F FDG PET/CT, and this helped the preoperative diagnosis be made. 18F 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.
