“…The prevalance of ETT is about 1 per 100,000-300,000 people, and 1 in 4,000 to 8,000 patients with the thyroid diseases and male to female ratio is 1/4 (14,15). However, in autopsy studies, the prevalence was found 7-10% (16,17). Ectopic thyroid tissue is most common in older than 40 years, especially in populations of Asian origin (18,19).…”

Objective: Ectopic thyroid tissue (ETT) is a rare abnormality of the thyroid gland and the true prevalence and importance is not known. The aim of this study was to evaluate ultrasonography (US) guided fine needle aspiration biposy (FNAB) results, sonographic features, and frequency of ETT detected in the midline of the neck. Subjects and methods: Five thousand five hundred and twenty outpatients who were referred to our thyroid clinic between September 2010 and April 2012 and underwent thyroid US, were retrospectively analyzed. Patients with ETT, detected in the midline of the neck in US were included in the study. Thyroid functions, sonographic features, and US guided FNAB results were evaluated. Results: There were 81 (81.8%) female and 18 (18.2%) male patients with a mean age of 50.9 ± 11.7. The ETT in the midline was present in 1.79% (99/5,520) of the patients. In the majority of the patients, benign sonographic features (isoechoic, regular margin, type 1 vascularization) were detected. There were 92 (92.9%) patients with a previous history of thyroidectomy and all were histopathologically benign. In 7 (7.1%) patients, there was no history of thyroid operation. FNAB results of ETT were benign. Conclusion: This study evaluated the importance of ETT detected incidentally in the midline of the neck. Especially in patients with a history of thyroidectomy, the thyroid masses in the midline of the neck can be found as incidental with imaging methods. Our results suggests that the incidence of malignancy in this group is much lower than orthotopic thyroid nodules and they are often benign. Arch Endocrinol Metab. 2016;60(3):231-5

“…Oropharyngeal examination showed a spherical mass at the back of the tongue but covered with intact mucosa measuring 3-2-2 cm. Thyroid hormone study reveals elevated TSH 43.54 mIU/L but with normal serum T 3 4 pml/L & T 4 9.3 pml/L level suggestive of hypothyroidism. Thyroid ultrasonogram report shows no thyroid tissue in thyroid bed, Thyroid spect scan by Tc99 shows thyroid gland not visualized in thyroid area.…”

“…Thyroid scan can also unmask additional sites of thyroid tissue. 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 4,11,15 .…”
