Bilateral benign non functional struma ovarii with Pseudo-Meigs' syndrome. Indian Journal of Pathology & Microbiology. 2009 Jan-Mar; 52(1): 94-6http://imsear.searo.who.int/handle/123456789/75313Bilateral presentation of benign Struma ovarii is rare and has not been reported frequently in published literature. A 70-year-old postmenopausal female presented with progressive ascites, bilateral pleural effusion and elevated CA-125 levels. The contrast-enhanced computed tomography (CECT) of the abdomen and pelvis revealed a heterogenous mass in the left adnexa. These findings were suspicious for an ovarian malignancy. After surgery the diagnosis of non functional, bilateral benign Struma ovarii was made. Struma ovarii is a specialized ovarian teratoma composed predominantly of mature thyroid tissue. It is associated with pleural effusion and ascites (Pseudo-Meigs' syndrome) in 5% of cases. The combination of struma ovarii and elevated CA-125 levels has been reported infrequently. This is a rare case of bilateral benign struma ovarii associated with Pseudo-Meigs' syndrome and elevated CA-125 levels. Surgical excision of the ovarian masses induced immediate resolution of the ascites and pleural effusion and a reduction of the serum CA-125 level.engAgedCA-125 Antigen --bloodFemaleHumansMeigs Syndrome --pathologyOvarian Neoplasms --diagnosisPelvis --radiographyRadiography, AbdominalStruma Ovarii --complicationsTomography, X-Ray ComputedCase Reports
