Imaging Findings in Lingual Thyroid: apropos of Two Cases
نویسندگان
چکیده
Lingual thyroid is a developmental anomaly caused by undescended thyroid tissue at the base of the tongue. Lingual thyroid is found predominantly in females and comprises 90% of ectopic thyroid tissue (1). In the majority of patients, the lingual thyroid is the only functioning thyroid gland tissue. Therefore early diagnosis with imaging techniques is clinically important to avoid permanent hypothyroidism following surgical removal. Imaging findings of this entity have previously been reported (2). We present two cases of lingual thyroid in order to emphasize the wide spectrum of radiological findings encountered in this rare developmental anomaly.

متن کاملLingual Thyroid: A Case Report and Literature Review
Thyroid ectopia is a dysgenesis of thyroid gland and Lingual position represents the most frequent ectopic location accounting up to 90% of ectopic cases. Hypothyroidism is commonly present because of absence of a normal thyroid gland in most instances. Primary hypothyroidism in juvenile population generally leads to retardation of linear growth and delay or even arrested puberty. We present a ...

large median endodermal anlage and two lateral anlages (1). Commonly, the median anlage fails to descend, resulting in a lingual thyroid gland. In rare cases, failure of the lateral anlage to fuse with the median anlage produces a lateral ectopic thyroid gland (2). There are a number of case reports of papillary thyroid carcinomas in ectopic thyroid tissue, but there are only a few cases of pri...

CONTEXT Lingual thyroid gland is a rare clinical entity that is caused by the failure of the thyroid gland to descend to a normal cervical location during embryogenesis. The occurrence of an ectopic thyroid gland located at the base of the tongue may cause problems for the patient, with symptoms of dysphagia, dysphonia, upper airway obstruction or even hemorrhage at any time from infancy throug...
