title: FDG PET/CT in serous psammocarcinoma of the ovary.
abstract: Serous psammocarcinoma of the ovary is a rare variant of ovarian serous carcinoma with a favorable prognosis. We present a case of bilateral ovarian serous psammocarcinoma showing extensive calcification in the primary and disseminated lesions with intense FDG uptake on FDG PET/CT. It may be difficult to differentiate the extensively calcified omental and peritoneal metastases from benign calcified lesions on CT images. This case indicates FDG PET/CT may have an advantage over conventional CT in differentiating malignant calcification from benign calcification based on glucose metabolic activity, and may be helpful for diagnosis and staging of this rare ovarian tumor.
