Meigs syndrome revisited.

The association of a benign ovarian tumor with ascites and hydrothorax that resolve after tumor resection is known as Meigs syndrome, and its importance was first emphasized by Meigs and Cass in 1937. The importance of Meigs syndrome is that the presence of ascites and pleural effusion does not necessarily indicate that a pelvic mass is malignant. The benign tumors in Meigs syndrome are usually fibromas or fibrothecomas and constitute 4% of all ovarian neoplasms. The authors present a case of Meigs syndrome with an ovarian fibroma. They focus on the evaluation of pleural fluid in the setting of an ovarian mass and then briefly discuss the imaging of ovarian fibromas and fibrothecomas.
