Evaluation and management of the lingual thyroid gland.
Lingual thyroid gland is a rare clinical entity that is due to failure of descent of the gland anlage early in the course of embryogenesis. It may present with symptoms of dysphagia, upper airway obstruction, or even hemorrhage at any time from infancy through adulthood. We present two illustrative cases of lingual thyroid gland along with a protocol for diagnosis and management of the condition. Elements in the diagnostic and therapeutic evaluation are described with attention to the clinical findings, laboratory tests, and radiographic imaging studies employed in confirming the diagnosis and planning appropriate treatment. The natural history of the condition is reviewed and a treatment strategy is outlined that focuses on the use of suppressive doses of thyroid hormone as the initial therapy. Surgical excision of the gland is reserved for more advanced cases of gland enlargement resulting in airway compromise, severe dysphagia that limits oral intake, or ongoing hemorrhage.
