Association of Pseudo-Meigs’ Syndrome with Struma Ovarii and High CA125 Mimicking Ovarian Malignancy

Abstract

Pseudo-Meigs’ syndrome (PMS) is a rare condition in which a non-fibroma ovarian tumor, pleural effusion, and ascites coexist, and in which removal of the tumor resolves the condition. We present here a patient with struma ovarii-associated PMS, and with high serum CA-125 levels, bearing a resemblance to a malignant ovarian tumor. Arriving at an accurate diagnosis prior to surgery and before to receiving the final pathology report is very difficult to achieve. However, this association must be considered when pleural effusion is found, in addition to a heterogeneous pelvic mass with a rise in CA-125 is evident.
