[A Case of Pseudo-Meigs Syndrome Associated with Metachronous Ovarian Metastasis from Ascending Colon Cancer].
We experienced a case of pseudo-Meigs syndrome associated with metachronous metastasis to the ovary from ascending colon cancer. A 65-year-old woman underwent curative surgery for ascending colon cancer at another hospital. A follow-up CT carried out 3 months after the surgery revealed a right ovarian tumor and a large amount of ascites. The patient was diagnosed with ovarian metastasis from ascending colon cancer with carcinomatous peritonitis. Palliative care was recommended, and she presented at our department for a second opinion. In spite of a large amount of ascites and pleural effusion, no disseminating tumor was detected on contrast-enhanced CT at our hospital, and we recommended that she undergo a diagnostic laparotomy. The laparotomy was negative for carcinomatous peritonitis and a right oophorectomy was performed. The histopathological findings indicated that the ovarian tumor was consistent with metastasis from ascending colon cancer. After the surgery, we initiated chemotherapy with mFOLFOX6+bevacizumab and the symptoms were well controlled. A follow-up CT carried out 11 months after the surgery revealed a left ovarian tumor and increased ascites, and the patient underwent a left oophorectomy. Then, chemotherapy with the same regimen was administered for 12 months, and she did not develop any signs of recurrence for 27 months after the surgery. Ovarian metastasis from colon cancer may occasionally cause pseudo-Meigs syndrome, and it is important to be aware of the usefulness of oophorectomy for the control of ascites and pleural effusion.
