Case report: Pseudo Meigs syndrome with uterine leiomyoma

Introduction: Meigs syndrome is an underdiagnosed pathology and should be suspected in the presence of an ovarian tumor associated with pleural and peritoneal effusion. In addition, it usually presents elevation of the tumor marker CA-125. All these clinical and analytical parameters improve after surgical removal of the tumor. Most cases are associated with benign ovarian tumors (fibroids). When it is associated with another type of ovarian/uterine tumor, whether benign or malignant, it is called << Pseudo Meigs Syndrome.>> >> The diagnostic confirmation of the tumor will be histological. Main symptoms and/or clinical findings: The clinical case of a patient is presented, in which a uterine tumor is observed that produces repetitive vasovagal syncope due to compression of pelvic organs, associated with right pleural effusion and ascites with mild-moderate elevation of CA-125. Main diagnoses: The main suspected diagnosis is Pseudo-Meigs syndrome, due to the association of a uterine tumor with pleural effusion and ascites. Therapeutic interventions and results: After resection of the tumor, which turned out to be a uterine leiomyoma, both effusions resolved and the tumor marker CA-125 normalized, corresponding to Pseudo Meigs Syndrome. Conclusion: In the differential diagnosis of a pleural effusion associated with ascites, the presence of an ovarian/uterine tumor must be ruled out, since, if observed, we could be dealing with Meigs/Pseudo Meigs Syndrome; which will be confirmed by the disappearance of the pleural effusion, ascites and normalization of the CA-125 marker after surgical resection of the tumor and which represents its resolution.
