Struma Ovarii: An Unusual Case Report

Abstract

Background:

Struma ovarii, an ovarian tumor, is diagnosed when >50% of the teratoma is thyroid tissue. Struma ovarii's incidence is <2% of mature teratoma.

Case:

We present a rare case report of struma ovarii of a 40-year-old female who presented with lower abdomen pain having right ovarian cyst on imaging study. Her cancer antigen (CA)-125 level was 18.70 units/mL and histologically proved to be struma ovarii.

Results:

Multicystic 7 × 6 cm ovarian mass was diagnosed as struma ovarii.

Conclusion:

Struma ovarii though a rare entity should always be kept in mind during ovarian neoplasm excision and should be cautiously searched for any malignant transformation.
