Dual thyroid ectopia with graves' disease: a case report and a review of the literature.

Ectopic thyroid or thyroid ectopia is a rare developmental anomaly with the prevalence of 1 per 100,000-300,000 population. Even rarer, such an anomaly manifests as dual thyroid ectopia. To our best knowledge, only one case has been reported on dual thyroid ectopia with Graves' disease in the English literature. We present here a case of dual thyroid ectopia complicated by Graves' disease, whereby the diagnosis was rendered through judicious use of various diagnostic modalities coupled with a close clinical follow-up. In this case, therapeutic consideration should be personalized with proper informed consent of the patient.
