For the vast majority of cases, surgical resection of the ovary is sufficient to treat benign, unilateral disease. A paucity of evidence exists in the literature regarding conservative management in cases with evidence of malignancy. In these patients, serum thyroglobulin levels can be followed as a marker for recurrence following fertility-sparing unilateral salpingo-oophorectomy. In patients who do not desire future fertility, malignant struma ovarii necessitates surgical staging for ovarian cancer with pelvic washings, total abdominal hysterectomy, bilateral salpingo-oophorectomy, lymph node sampling, total thyroidectomy, and radioactive I-131 ablation. The recurrence rate in patients with malignant struma ovarii who undergo surgery without subsequent radioablation has been cited as high as 50%. [15]
