Struma ovarii is the presence of thyroid tissue as a major cellular component in an ovarian teratoma and it is usually benign but malignant changes has been reported in 3%–5% of all Struma ovarii tumors [1,2]. The symptoms of Struma ovarii are similar to those of other ovarian tumors and are nonspecific in nature. The tumor can be characterized by imaging, but the final diagnosis is made by pathological and histological examination. Surgical resection remains the definitive treatment for benign disease. Our case is 47 -year-old old multiparous woman, who presented with a palpable pelvic mass and symptoms of pelvic discomfort and vague abdominal pain. The pelvic ultrasound showed a large complex ovarian mass with cystic and solid component with no suspicion of malignancy. She underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Histology showed Struma ovarii. Post operatively the patient did very well with no complications and TFT was normal.
