“…Interestingly, lingual thyroid has been found in 10% of 200 consecutive autopsies (15). The most common symptoms are related to the growth of lingual thyroid and include dysphagia, dysphonia, stomatolalia (speech that is produced with clogged nostrils), sensation of foreign body, cough, snoring, sleep apnea (16)(17)(18)(19)(20), and, in more severe cases, respiratory obstruction and hemorrhage (21). The patient may be also asymptomatic; thus, lingual thyroid may be an incidental finding, revealed after investigation of non-thyroid-related symptoms (22).…”

“…Thyroid scan can also unmask additional sites of thyroid tissue. It is both sensitive and specific for differentiation of an ectopic thyroid from other causes of midline neck masses (4,16,20,61). However, the possibility of false positive diagnostic iodine scans must be taken into account, as a result of either normal or abnormal uptake in the head and neck.…”

“…Radiological imaging modalities, such as grayscale or color Doppler US, computed tomography (CT), and magnetic resonance imaging (MRI), may help in designating the extension and location of ectopic tissue, thus contributing to a better pre-surgical evaluation of these cases (4,16,20,61,73,74). Sometimes, chest radiography may also be useful in revealing some cases of intrathoracic goiter (34).…”

Ectopic thyroid tissue is a rare entity resulting from developmental defects at early stages of thyroid gland embryogenesis, during its passage from the floor of the primitive foregut to its final pre-tracheal position. It is frequently found around the course of the thyroglossal duct or laterally in the neck, as well as in distant places such as the mediastinum and the subdiaphragmatic organs. Although most cases are asymptomatic, symptoms related to tumor size and its relationship with surrounding tissues may also appear. Any disease affecting the thyroid gland may also involve the ectopic thyroid, including malignancy. The clinician must distinguish between ectopic thyroid and metastatic deposits emerging from an orthotopic gland, as well as other benign or malignant masses. Thyroid scintigraphy plays the most important role in diagnosing ectopy, but ultrasonography contributes as well. In cases of symptomatic disease, surgery is the treatment of choice, followed by radioiodine ablation and levothyroxine suppression therapy in more refractory cases. This review provides current understanding about the wide clinical spectrum of this rare condition, also referring to optimal diagnostic approach, differential diagnosis, and management strategies.

Despite the fact that TSH screening in newborns is currently conducted in most developed countries, patients with thyroid ectopy born before the procedure was introduced or those in whom the screening failed to establish diagnosis, might still appear. In this paper we revise the current state of knowledge regarding the clinical presentation, diagnosis, and treatment of patients with thyroid ectopy. As an example, we report diagnostic and therapeutic difficulties in our three patients with thyroid ectopy remaining undiagnosed and untreated during early childhood. Introduction of neonatal screening for congenital hypothyroidism does not guarantee that all patients with thyroid ectopy will be correctly diagnosed and properly treated, due to the possibility of falsely negative results of TSH screening or lack of compliance from parents. Visualisation of an ectopic thyroid on ultrasound examination may be challenging for unexperienced sonographers; muscles in the thyroid bed may be misdiagnosed as heterogeneous and hypoechogenic thyroid gland with features suggesting autoimmune thyroid disease. Thyroid scintiscan is crucial for confirmation of the diagnosis of thyroid ectopy.In conclusion, hypothyroidism due to thyroid developmental anomaly should be taken into consideration in cases of hypothyroidism and normal thyroid autoantibodies in a patient at any age.

“…The prevalence of lingual thyroid varies from 1:100,000 to 1:300,000 and may remain undiagnosed for a long period in life [3]. It is reported as being 4-8 times more common in females [4]. The average age at presentation was 40.5 years with statistically significant peak at 12.5 and 50 years.…”

Lingual thyroid: an unusual and surgically curable cause of sleep apnoea in a male

Abstract: This is the first time a lingual thyroid causing sleep apnoea has been studied with pre- and post-treatment sleep studies. This is also the first recorded instance of lingual thyroid causing sleep apnoea has been recorded in a male.
