PEREIRA, Joana Araújo et al. Struma ovarii: clinic presentation with Pseudo-Meigs Syndrom. []. , 17, 1, pp.85-88.   31--2023. ISSN 1646-5830.

Struma ovarii is a form of mature teratoma consisting predominantly of thyroid tissue. In 5% of the cases, it may occur with ascites (20%) and pleural effusion, constituting the Pseudo-Meigs Syndrome. We describe the case of a 62-year-old woman monitored at a Pulmonology consultation for dyspnea on moderate exertion and parapneumonic pleural effusion with a one-year evolution of non-malignant etiology. Ascites and solid adnexal lesion with increased cancer antigen-125 (1475.8 U/ml) were diagnosed . Histological examination revealed a lesion with characteristics of struma ovarii, with no signs of malignancy. Being a benign disease case, the prognosis is excellent.
