Struma ovarii is a rare tumour, most commonly found as part of a mature cystic teratoma (dermoid cyst). The thyroid tissue component comprises more than 50% of the total mass. Struma ovarii is often asymptomatic and found accidentally; it might, however, present symptoms like other ovarian tumours. In approximately 5% of the cases patients may show symptoms of hyperthyroidism or thyrotoxicosis. Treatment comprises surgical removal. In the presented case the patient developed biochemical signs of hypothyroidism after the operation. It is recommended that thyroid function should be controlled after treatment.
