:''Not to be confused with Meige syndrome'' In medicine, Meigs' syndrome, also Meigs syndrome, is the triad of ascites, pleural effusion and benign ovarian tumor (fibroma, Brenner tumour and occasionally granulosa cell tumour). It resolves after the resection of the tumor. Because the transdiaphragmatic lymphatic channels are larger in diameter on the right, the pleural effusion is classically on the right side. The etiologies of the ascites and pleural effusion are poorly understood.〔 Atypical Meigs' syndrome, characterized by a benign pelvic mass with right-sided pleural effusion but without ascites, can also occur. As in Meigs syndrome, pleural effusion resolves after removal of the pelvic mass.〔 ==Differential diagnosis== It may mimic other conditions,since it is tumor arising from ovaries, pathology of any organs present in the abdomen may show similar set of symptoms.Various gynecological disorders of uterus such as endometrial tumor, sarcoma, leiomyoma (pseudo-Meigs' syndrome), Fallopian tubules disorders such as Hydrosalpinx,granulomatous salpingitis, fallopian tube malignancy, ovarian disorders such as benign, serous, mucinous, endometrioid, clear cell, Brenner tumor, granulosa, stromal, dysgerminoma, fibroma, metastatic tumor. Meigs' syndrome is characterized by the presence of a benign solid ovarian tumor associated with ascites and right hydrothorax that disappear after tumor removal. Non-gynecological disorders include: Ascites, Portal Vein Obstruction, IVC obstruction, Hypoproteinaemia, Thoracic duct obstruction, TB, Amyloidosis, Pancreatitis, Neoplasm, Ovarian hyperstimulation, Pleural effusion transudative, CHF, Malignancy metastatic tumors to the peritoneal surfaces, Collagen-vascular disease, Cirrhosis liver failure. These entities must be clinically excluded. Clinical condition characterized by ovarian mass, ascites, and right-sided pleural effusion.Ovarian malignancy and the other causes (see “Differential Diagnosis”) of pelvic mass, ascites, and pleural effusion to be considered, History of early satiety, weight loss with increased abdominal girth, bloating, intermittent abdominal pain, dyspnea, nonproductive cough may help in differentiating potential local factor causing such symptoms. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Meigs' syndrome」の詳細全文を読む スポンサード リンク
