Pseudo-Meigs' syndrome secondary to isolated colorectal metastasis to ovary: a case report and review of the literature.
BACKGROUND
Pseudo-Meigs' syndrome is a syndrome that includes hydrothorax and/or ascites secondary to ovarian neoplasms other than benign primary tumors. Gastrointestinal malignancies, including colorectal or gastric adenocarcinoma, are rare etiologies for this syndrome.


METHODS
In this report, we present the case of a 49-year-old woman with metastatic colon cancer who acutely developed a massive pleural effusion and ascites coincident with a rapidly enlarging adnexal mass and a rising CA-125 level.


CONCLUSIONS
Seven cases of pseudo-Meigs' syndrome secondary to gastrointestinal primaries have been reported to date. This case highlights the difficulty in discerning the diagnosis of pseudo-Meigs' syndrome from that of disseminated colorectal cancer or a new primary ovarian neoplasm and the importance in making the distinction to initiate appropriate therapy.
