Abstract:
Dual ectopic lingual and sublingual thyroid gland is an extraordinarily rare condition. We present 1 patient with subclinical hypothyroidism. The clinical examination revealed that the thyroid gland was not palpable in its usual cervical location, whereas ultrasonography confirmed an empty thyroid bed without any ectopic thyroid tissue in the rest of the neck. The final diagnosis of dual ectopic lingual and sublingual thyroid was established by ultrasound examination through the mouth floor and confirmed by scintigraphy and CT thereafter.
