“…Struma ovarii is very uncommon, accounting for less than 3% of all mature cystic ovarian teratomas ( 3 ). Pre-operative diagnosis is difficult, because this rare tumor has no differentiating signs or symptoms ( 6 , 7 ). Imaging modalities such as ultrasound, CT, MRI, and scintigraphy of the pelvis can make the diagnosis when suspicion of struma ovarii exists.…”

A postmenopausal female presented with an enlarging multinodular goiter. Microcalcifications within the largest thyroid nodule found by ultrasound prompted her to elect a total thyroidectomy. Histopathologic evaluation led to the diagnosis of confined papillary thyroid carcinoma (follicular variant). Elevated serum thyroglobulin levels were noted on postoperative laboratory workup, with the differential diagnosis of residual thyroid tissue, substernal extension of an adenomatoid multinodular goiter, and/or metastatic thyroid cancer. The patient then underwent thyrogen-stimulated I-131 ablation therapy, with postablation scans detecting a solitary focus of intensely increased radiotracer accumulation in the midline pelvis. Ultrasound of the pelvis revealed a corresponding right ovarian mass with mixed solid and cystic components. These combined findings were highly suggestive of struma ovarii. An exploratory laparotomy/bilateral salpingo-oophorectomy was performed, and pathologic examination confirmed a mature teratoma with predominant benign thyroid component consistent with struma ovarii.

Case summary-Struma ovarii is a rare type of ovarian teratoma comprised of mainly of thyroid tissue that does not typically alter thyroid hormone levels and uncommonly recurs or persists after ovarian cystectomy. We report a case of struma ovarii causing hyperthyroidism, co-incident with Hashimoto's thyroiditis. The patient had a history of asymptomatic struma ovarii found at laparoscopic surgery, which had been removed by ovarian cystectomy 3 years earlier. In a patient with two different causes of abnormal thyroid function, it is important to seek an encompassing clinical scenario; in this instance, we identified an extraglandular cause of hyperthyroidism concomitant with an underactive thyroid gland.Objective-To report the identification of struma ovarii in a patient with a history of struma ovarii and new hyperthyroidism Design-Case report Setting-Academic research hospital Patient(s)-A woman with hyperthyroidism who has struma ovarii, co-incident with Hashimoto's thyroiditis Interventions-Laparoscopic salpingo-oophorectomy Main Outcome Measure(s)-Measurement of thyroid hormone parameters before and after surgeryResult(s)-After removal of the second struma ovarii, hyperthyroidism resolved. We describe a patient who developed new clinical hyperthyroidism coincident with Hashimoto's thyroiditis; a history of struma ovarii facilitated the diagnosis of an ovarian tumor, and the ovary was removed. Conclusion(s)-In
