Abstract

We report a rare case of Pseudo-Meigs’ Syndrome caused by ovarian metastasis from sigmoid colon cancer, which was accompanied by peritoneal dissemination. A 58-year-old female patient presented with massive right pleural effusion, ascites and a huge pelvic mass. Under the diagnosis of an advanced ovarian tumor, bilateral oophorectomy was performed and sigmoidectomy was also carried out after intraoperative diagnosis of peritoneal dissemination involving the sigmoid colon. However, immunohistochemical staining revealed that the ovarian lesions were metastasis from the primary advanced colon cancer. Postoperatively, ascites and pleural effusion subsided, and the diagnosis of Pseudo-Meigs’ Syndrome due to a metastatic ovarian tumor from colon cancer was determined. The patient is now undergoing a regimen of chemotherapy for colon cancer without recurrence of ascites or hydrothorax 10 mo after the surgery. Pseudo-Meigs’ Syndrome due to a metastatic ovarian tumor from colon cancer is rare but clinically important because long-term alleviation of symptoms can be achieved by surgical resection. This case report suggests that selected patients, even with peritoneal dissemination, may obtain palliation from surgical resection of metastatic ovarian tumors.
