Leiomyoma causing massive ascites, right pleural effusion and respiratory distress. A case report.

BACKGROUND: Pseudo-Meigs' syndrome, or atypical Meigs' syndrome, occurs when a pelvic mass other than an ovarian fibroma is present with hydrothorax and ascites. Leiomyomas rarely cause this condition. CASE: An otherwise healthy 31-year-old woman presented to the emergency department in acute respiratory distress with massive ascites, pleural effusion and a pedunculated leiomyoma. After receiving mechanical ventilation, she underwent myomectomy and recovered fully within four weeks. CONCLUSION: This unique presentation of pseudo-Meigs' syndrome should be included with malignancy in the differential diagnosis of a pelvic mass with ascites.
