Pseudo-Meigs' syndrome due to broad ligament leiomyoma: a mimic of metastatic ovarian carcinoma.

Pseudo-Meigs' syndrome is a rare complication of benign leiomyomas of the female genital tract. We report a patient with pseudo-Meigs' syndrome due to a large broad ligament leiomyoma, which also caused bilateral reversible hydronephrosis. This unusual combination of pseudo-Meigs' syndrome, broad ligament leiomyoma and hydronephrosis requiring ureteric stenting does not appear to have been reported previously. Features of the syndrome that led to a diagnostic problem, the mimicking of metastatic ovarian carcinoma, are presented. The little that is known of the pathogenesis of the pleural and ascitic fluids is discussed. An elevated level of serum CA 125 antigen is reported, we believe for the first time in association with pseudo-Meigs' syndrome.
