Secondary massive ovarian edema with Meig's syndrome.

Primary massive ovarian edema is uncommon, particularly when it involves both ovaries before puberty. Ovarian edema secondary to a preexisting ovarian lesion is one of the postulated mechanisms. A prepubertal girl presented with bilateral massive ovarian edema with stromal hyperthecosis, which may have predisposed both ovaries to undergo partial torsion. The associations with Meig's syndrome, greatly elevated hormone levels and presence of omental and retroperitoneal nodules, raised a suspicion of malignancy.
