{Reference Type}: Case Reports {Title}: Pseudo-Meigs' Syndrome With Eosinophilic Pleural Effusion. {Author}: Shimoda M;Tanaka Y;Morimoto K;Moue I;Ohta K; {Journal}: Cureus {Volume}: 16 {Issue}: 2 {Year}: 2024 Feb 暂无{DOI}: 10.7759/cureus.54686 {Abstract}: We present a rare case of a 45-year-old woman with pseudo-Meigs' syndrome and eosinophilic pleural effusion (EPE). She experienced cough, sputum, and dyspnea with a large right pleural effusion. Laboratory tests showed eosinophilia in the blood and pleural fluid. An ovarian tumor and ascites were also detected. After left salpingo-oophorectomy, the tumor was diagnosed as a mature cystic teratoma of the left ovary. The right-sided pleural effusion gradually resolved. Pseudo-Meigs' syndrome is characterized by benign ovarian tumor, ascites, and pleural effusion. Typically, it is associated with exudate pleural effusion characterized by a predominance of mononuclear cells. The occurrence of eosinophilic pleural effusion in our patient may be exceptionally rare.
