Abstract

Ovarian goiter is a rare tumor of the ovary that is characterized by a presence of thyroid tissue in the ovary and occupies more than 50% of the total mass of the tumor. It is accompanied by ascites in the 1/3 of cases. Τhe combination of struma ovarii, ascites and increased levels of CA125 is extremely rare. We report a case of a 77 years old woman with ascites, a big mass on the left ovary and increased levels of CA125, which are signs and symptoms of malignant tumor of the ovary.The patient underwent surgical removal of tumor with rapid remission of the ascites and decrease of the levels of CA125. Struma ovarii can imitate a malignant tumor of the ovary, especially when it is accompanied by ascites and increased levels of CA125.

Keywords: ovarian goiter, struma ovarii, ascites, thyroid tissue, CA125
