Ovarian Goiter as a Rare Cause of Hyperthyroidism

Acta Endo (Buc) 2016, 12 (3): 335-338
doi: 10.4183/aeb.2016.335

Thyroid tissue ectopically located in the ovary can be reported accidentally after adnexectomy, but as a primary cause of hyperthyroidism this diagnosis is rare. The clinical search for a functional ectopic thyroid tissue requires intense clinical focus and a multidisciplinary approach. Case Description. This case report demonstrates a patient with a history of Graves’ disease who had undergone thyroidectomy combined with postoperative 131I radioablation. Despite the previous treatment, she developed an outburst of hyperthyroidism ten years later. Only very close follow-up enabled us to disclose the right condition. The ovarian source of thyroid hormone production was removed by laparoscopic adnexectomy and a right sided benign ovarian struma was confirmed. Conclusion. Most patients treated by thyroidectomy and radioiodine do not require extended periods of followup or postoperative investigations, but when the clinical or laboratory signs change, clinicians should be prepared to perform the necessary re-evaluation in order to provide the best care.
