Abstract

The association of pseudo-Meigs' syndrome, elevation of CA 125 to the struma ovarii is a rare condition. So far only nine cases have been reported in English literature through MEDLINE search. Here we report a 46-year-old case of the struma ovarii, presented with ascites, hydrothorax, right ovarian mass and elevated serum CA 125 level. These findings were misdiagnosed for an ovarian malignancy at the first impression. Immediate resolution of the ascites, hydrothorax and normalization of the serum CA 125 level were followed by ovarian mass removal. Struma ovarii could be a rare cause of ascites, hydrothorax, ovarian mass and elevated CA 125. This rare condition should be considered in the differential diagnosis in patents with ascites and pleural effusions but with negative cytology.
