A case of pseudo-Meigs' syndrome caused by metastatic ovarian tumor from gastric cancer during pregnancy

Pseudo-Meigs’ syndrome is a syndrome that includes hydrothorax and ascites secondary to ovarian tumors other than solid benign fibroma. In this report, we present the case of a 29-years-old female who complained of abdominal distension with peripheral edema during her third trimester. Two solid masses of 15 cm dimension in the left abdomen and 7 cm dimension in the right abdomen were detected by ultrasound and chest X-ray revealed right pleural effusion. Magnetic resonance imaging (MRI) confirmed the ovarian masses and ascites. As the patient had regular uterine contractions, we decided to perform emergency cesarean section because of previous cesarean section history. A laparotomy was performed and pathologists confirmed the presence of a metastatic adenocarcinoma. Four days following the surgery, gastroduodenoscopy revealed a huge ulcerofungating mass was visible in greater curvature of stomach. The final diagnosis was metastatic adenocarcinoma from gastric cancer. Although pseudo-Meigs’ syndrome is very rare, it should be carefully considered when evaluating female complaining with ascites in ovarian tumor.
