A 34-year-old woman presented with a 2-year history of anterior midline neck swelling. The physical examination revealed a soft, mobile, nontender, 2 × 1 cm, anterior midline neck mass. Ultrasonography showed a heterogeneously isoechoic mass (2.23 × 1.18 cm) in the subhyoid region, while a thyroid gland was not seen in the normal position (Fig. 1A). A 99mTc-pertechnetate scan demonstrated two d...

The thyroglossal Duct (TD) cyst results from a failure in obliterating the embryogenic duct produced during thyroid migration. A cyst may develop from the secretory residual epithelium. Ectopic thyroid tissue neoplasias are rare, and even rarer when associated with the TD. It has been reported that over 7% of adults have some remains of the TD1 and over 62% of them may have some ectopic thyroid...

Thyroid develops from median rudiment which is a surface elevation dorsal to the tuberculam impar and forms by proliferation of endodermal cells. Lateral thyroid element of the fourth pouch contributes in the development of thyroid gland. Failure of the lateral thyroid element to fuse with the median element may result in a lateral ectopic thyroid gland. In the present case, patient initially p...

The aim of this study was to report a rare case of non-functional ectopic thyroid tissue in the neck with a coexisting normal thyroid. A 36-year-old female presented with a mass in the anterior neck. The thyroid function of the patient was normal. Ultrasonography and computed tomography (CT) revealed a normal thyroid gland and a solid mass in the middle lower neck. Scintigraphy showed a normal ...

BACKGROUND Evaluation of thyroglossal duct cysts before surgical excision traditionally includes hormonal evaluation, ultrasound of the neck, and thyroid scanning. OBJECTIVE To evaluate the need for thyroid scanning in cases of thyroglossal duct cysts scheduled for operation. METHODS A retrospective chart review of 100 cases of thyroglossal duct cyst between 1988 and 1995 was carried out. ...

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 ...
