RESUMEN
Demons-Meigs syndrome is a rare clinical presentation of benign ovarian mass with hydrothorax and ascites. As ascites can be present in any ovarian mass, hydrothorax is a salient feature of the syndrome. The syndrome is subtyped as atypical in the absence of ascites from the triad. Nevertheless, it is labeled as pseudo-Demons-Meigs syndrome if the ovarian tumor is neoplastic rather than benign. The management of Demons-Meigs syndrome is complex and could be misleading due to pleural effusion and ascites, so an understanding of the syndrome is important. This case report is unique as it has two rare findings of neoplastic tumor and absence of ascites. Furthermore, this case is distinct as both ovaries are involved in malignant granulosa theca cell tumor with right-sided pleural effusion without ascites.
