A Rare Case of Synchronous Lobular Breast Carcinoma and Serous Psammocarcinoma of the Ovary Evaluated by 18F-FDG PET/CT.

Abstract

Serous psammocarcinoma of the ovary is a rare variant of ovarian serous carcinoma characterized by the presence of calcified peritoneal lesions, known as psammoma bodies. These calcified lesions may usually be considered benign on computed tomography but may show avidity for ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG), which can be helpful in the diagnosis of this rare ovarian tumor. We present a rare case of serous psammocarcinoma of the ovary detected during the diagnostic work-up of lobular breast cancer using ¹⁸F-FDG positron emission tomography/computed tomography.
