Struma ovarii, a rare varity of ovarian neoplasm, belongs to the group of monodermic teratomas mainly composed of thyroid tissue. The preoperative diagnosis is always difficult to identify without histopathological examination. Surgery is the only treatment because malignant alteration is possible and thyroid hyperactivity or hyperthyroidism may occur. Our patient, a post-menopausal women, had unilateral, large, multiloculated ovary mass of 20cm×15cm×10cm size without any thyroid hyper activity. The radical excision of the tumor with right ovary was preformed. Histopathological examination confirmed struma ovarii. The post-operative period was uneventful and her thyroid function remained normal.
