A rare case of Demons-Meigs' syndrome with a 7.5 kg giant ovarian fibroma associated with severe dyspnea: case report.

INTRODUCTION AND

IMPORTANCE

Demons-Meigs syndrome is a rare condition characterized by the presence of a benign fibroma of the ovary, ascites, and pleural effusion. It is very uncommon, and the diagnosis is made with difficulty based on symptoms that usually mimic disseminated malignancy or tuberculosis, but imaging may confirm the diagnosis. The definitive treatment is laparotomy, after which the symptoms resolve.

CASE PRESENTATION: We present a 36-year-old female with Demons-Meigs' syndrome with severe dyspnea who underwent an abdominal surgical exploration, which revealed ascites of 1500 ml and an ovarian fibroma weighing 7.5 kg and measuring 12 cm in length. There were no postoperative complications. CA-125 was undetectable at 3 months post-procedure.

CLINICAL DISCUSSION: The most common symptoms are dyspnea, fever, fatigue, and weight loss. In low- and middle-income countries, patients usually present with late-stage disease. The treatment of choice for Demons-Meigs' syndrome is exploratory laparotomy.

CONCLUSION

This tumor is often misdiagnosed as a uterine myoma on sonography. The symptoms resolved, and the patient became asymptomatic after laparotomy and thoracocentesis. For this reason, when patients present with effusion and an abdominal mass, a thorough assessment should be done to confirm if it is Demons-Meigs' syndrome, which can be completely cured by the removal of the tumor.
