[Pseudo-Meigs syndrome: particular management of ovarian metastases in colorectal cancer]. / Le pseudosyndrome de Meigs, particularité dans la prise en charge des métastases ovariennes de cancer colorectal.

Ascites and/or pleural effusion with ovarian metastases in colorectal cancer are usually related to peritoneal carcinomatosis. Pseudo-Meigs syndrome is a characterized by non-malignant ascites and/or pleural effusion caused by pelvic tumors other than solid benign ovarian tumors. We treated two patients who developed this syndrome in a context of colorectal cancer. After ovarian metastasis resection, ascites and pleural diffusion disappeared. In the presence of acellular ascites with ovarian metastases from colorectal cancer, diagnosis of pseudo-Meigs syndrome may allow surgical treatment with curative intent.
