Imaging of ectopic thyroid tissue and thyroglossal duct cysts.

Zander DA1, Smoker WR.Author information 1From the Department of Radiology, University of Iowa Hospitals and Clinics, 200 Hawkins Dr, Iowa City, IA 52242.AbstractWhen a child or young adult presents with a mass in the anterior portion of the neck, diagnostic considerations include a thyroglossal duct cyst and ectopic thyroid tissue. These entities are often suspected clinically, and imaging provides an opportunity to evaluate the extent, confirm the diagnosis, and evaluate for complications. Imaging characteristics of a thyroglossal duct cyst as a simple cyst and of ectopic thyroid tissue as a hyperattenuating soft-tissue mass can help identify these lesions at computed tomography (CT); however, intrinsic magnetic resonance, CT, and ultrasonographic imaging characteristics alone cannot be used to confirm the diagnosis. Rather, knowledge of the typical course of the thyroid primordium during embryologic development is essential to understand the variant locations along this path where thyroid tissue can be found. The migration of thyroid primordium begins at the foramen cecum at the base of the tongue and then loops around the hyoid bone anteriorly and inferiorly and descends anteriorly to the thyrohyoid membrane into the orthotopic location in the infrahyoid portion of the neck. Thyroid ectopia is categorized into one of four typical locations with respect to this embryologic course: (a) the base of the tongue, (b) adjacent to the hyoid bone, (c) the midline infrahyoid portion of the neck, and, rarely, (d) the lateral part of the neck. The differential diagnosis includes metastatic thyroid carcinoma, branchial cleft cyst, lymphatic malformation, abscess, saccular cyst, epidermoid cyst, and squamous cell carcinoma. The relationship of a mass to landmarks such as the foramen cecum, hyoid bone, strap muscles, thyrohyoid membrane, and thyroid cartilage can help differentiate a thyroglossal duct cyst and ectopic thyroid tissue from other anterior neck masses when the embryologic thyroid course is considered.

Hashimoto's thyroiditis: an accidental discovery of a lingual thyroid in a 7-year-old child.

Mariani M1, Palpacelli A, Mussoni A, Rossodivita AN.Author information 1Department of Paediatrics, Catholic University, Rome, Italy.AbstractAn ectopic thyroid located at the base of the tongue is a rare entity, resulting from early developmental defects of thyroid gland embryogenesis during its descent from the foramen caecum to its normal eutopic pretracheal site. This condition is the main cause of congenital primary hypothyroidism, even though signs and symptoms of thyroid dysfunction may also appear later in childhood. Lingual thyroid may sometimes present with symptoms of respiratory obstruction or feeding difficulties. We illustrate the case of a 7-year-old girl with subclinical hypothyroidism due to Hashimoto's thyroiditis arising in a lingual thyroid. She had never suffered from upper airway obstructive symptoms, but did refer a 3-month history of cough. Rapid normalisation of thyroid-stimulating hormone levels and termination of the cough were attained when the L-thyroxine treatment started. After 6 months a significant reduction of lingual thyroid size was also noted. The diagnostic procedures and therapeutic options in childhood are discussed.

Endoscope-assisted intraoral removal of ectopic thyroid tissue using a frenotomy incision.

Woo SH1, Jeong HS, Kim JP, Park JJ, Baek CH.Author information 1Department of Otolaryngology, Gyeongsang National University , Jinju, Korea.AbstractBACKGROUND: Ectopic thyroid tissue is a relatively rare condition and a developmental anomaly characterized by the aggregation of thyroid tissue. Usually, it occurs along the path of descent of the developing thyroid primordium from the foramen caecum, the most common being in the anterior midline of the neck at or below the level of the hyoid bone. Surgical removal of ectopic thyroid tissue is usually accomplished through an external incision in the neck. However, this procedure inevitably results in a neck scar.
