Demons-Meigs syndrome caused by a giant ovarian fibroma: A case report.

ABSTRACT

Demons-Meigs syndrome is a very rare entity. It combines a benign ovarian "fibroma-like" tumor with ascites and hydrothorax. The notion of benignancy is the key point. CA-125 levels are most of the time normal, but high levels can be observed in rare cases which makes it difficult to have a diagnostic. We present here the case of a 43-year-old female patient who presented with abdominopelvic pain. Imaging discovered a 30 cm large intraabdominal mass with ascites and bilateral pleural effusion. Surgical resection of the tumor was performed, and pathology identified an ovarian fibroma. No postintervention complications were observed, with resorption of the ascites and hydrothorax.
