Ectopic Thyroid Mimicking A Thyroglossal Duct Cyst: A Case Report

Abstract

Thyroid ectopy is a rare condition, caused by dysfunction during migration of the thyroid gland during its embryogenesis. It is generally associated with subclinical hypothyroidism. Patients with this pathology are mostly asymptomatic. It is seen in childhood by an anterior cervical mass which confuses it with a cyst of the thyroglossal tract. The diagnosis is made by ultrasound imaging, scintigraphy and histological examination. Management is essentially hormonal. Surgery is considered in case of complication.
