Meig's syndrome in a young woman: a case report

Meig’s syndrome is a triad of "ovarian benign tumor, ascites and plural effusion" and the patient refers with a probable malignant ovarian mass, but it is benign; and the symptoms would be vanished by eliminating the tumor. As this is a rare syndrome, we decided to present this case.
A 26 years old virgin girl with an abdominal mass and stable vital signs referred to Gynecology clinic of Imam Reza hospital. A pelvic mobile mass, sized 18 weeks of pregnancy was palpated. Sonography reported a solid pelvic mass with cystic components around 140×100 mm that indicated either submucosal pedanculated uterine fibroma or right ovarian mass. Ascites and right pleural effusion were reported in the second ultrasonography. Tumor markers except CA125 were normal. One liter of ascites fluid was evacuated during surgery. A 150×170 mm ovarian tumor in the ovary with a complete capsule without adhesion was obtained. Benign ovarian fibrothecoma was confirmed by frozen section. The permanent pathology report was benign ovarian fibroma. The peritoneal fluid cytology, left ovarian biopsy, diaphragmatic and paracolic groove specimens were normal. The patient was fine two weeks after surgery with no pleural effusion and ascites.
Although combination of ascites and elevated CA125 with a pelvic mass mostly indicates an ovarian malignancy, but Meig's syndrome must be considered in young women. So, ascites and pleural effusion and elevated CA125 in combination with a solid ovarian tumor is not always an indicator of a malignancy especially in young women.
