[Ascites, pleural effusion and a benign ovarian tumour; the triad of Meigs' syndrome].

BACKGROUND: Classical Meigs' syndrome consists of the triad of an ovarian fibroma, ascites and pleural effusion. A characteristic of the syndrome is that the excess fluid is resorbed after surgical resection of the tumour. CASE DESCRIPTION: A 49-year-old woman was admitted to accident and emergency department in a neglected, cachectic and hypothermic condition. A CT scan revealed an ovarian tumour, ascites and a right-sided pleural effusion. The level of the tumour marker CA-125 was also greatly elevated. Our initial working diagnosis was, therefore, 'high-grade ovarian carcinoma', but on repeated testing no malignant cells were found in the aspirated fluid. We suspected Meigs' syndrome. We first ensured that her general and nutritional condition improved; then she underwent a bilateral adnexectomy. A fibrothecoma was found in each ovary. The ascites and pleural effusion resolved following surgery and the patient recovered well. CONCLUSION: The clinical picture of Meigs' syndrome can resemble that of high-grade ovarian carcinoma. This syndrome should be included in the differential diagnosis in patients with an ovarian tumour, ascites and, possibly, pleural effusion.
