BACKGROUND Lingual thyroid represents 90% of ectopic thyroid tissue localizations. The first case was described by Hickman in 1869. An ectopic thyroid is often asymptomatic, but pathological or physiological conditions inducing hyperproduction of thyroid-stimulating hormone can lead an ectopic thyroid to become symptomatic. Treatment of the symptomatic ectopic thyroid can be medical, with hormo...

Ectopic thyroid is an uncommon embryological aberration of the thyroid descent. Subhyoid median ectopic thyroid gland is a result of incomplete descent of the thyroid anlage and is characterized by a cosmetically unacceptable ovoid mass of thyroid tissue in the midline overlying the thyroid cartilage and thyrohyoid membrane. A normally placed thyroid gland is not detectable and in most cases al...

BACKGROUND Surgical excision of an ectopic lingual thyroid has traditionally been associated with significant morbidity and has therefore been reserved for patients with severe obstructive symptoms or suspected malignancy. Transoral robotic surgery (TORS) has provided a minimally invasive approach to completely and safely excise ectopic lingual thyroid. METHODS Three index cases were identifi...

UNLABELLED Ectopic thyroid goiter accounts approximately for 1% of all substernal goiters and for 10-15% of all mediastinal masses. Sternotomy is generally accepted as the most adequate approach for the removal of ectopic thyroid goiters of the anterior mediastinum. We report two cases of mediastinal ectopic goiter removal through a cervical incision, without sternotomy. The technique is based ...

Rationale: Ectopic thyroid is commonly found in the neck region. Intra-abdominal ectopic thyroid is extremely rare, with only 2 cases reported in the pancreatic region. Very few reports have described detailed imaging findings of intra-abdominal ectopic thyroid. Patientconcerns:A 73-year-old womanwith aggravated recurrent right upper quadrant pain was found to have a retroperitoneal mass at the...

We report here a rare case of lateral ectopia of thyroid without orthotopic thyroid tissue in an Indian teenager, who was referred to our department for a thyroid scintigraphy. Technetium Pertechnetate (99mTcO4- ) scan showed uptake in laterally placed soft tissue structure along with functioning thyroid tissue in high anterior midline neck region in line with thyroglossal...

We report a case of papillary carcinoma in a mediastinal ectopic thyroid diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this case, the tumor was adjacent to the central airway; therefore, we attempted to perform EBUS-TBNA to obtain specimens for a diagnosis of papillary thyroid carcinoma. Surgical resection was conducted, and histological evaluatio...

INTRODUCTION Hyperthyroidism is a syndrome caused by the excessive production and secretion of the thyroid hormones T3 and T4 by an autonomous thyroid gland. Feline hyperthyroidism was first reported in 1979 and since then it has become a common disease in cats. Histopathology of affected thyroids usually reveals thyroid hyperplasia or benign thyroid adenoma, however in a small percentage of ca...

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...

Ectopic thyroid tissue may be observed anywhere from the tongue base to the lower neck. It is rarely seen in the mediastinum and abdominal cavity. Computed tomography and magnetic resonance imaging are very sensitive for detection and localization of ectopic thyroid tissue. This pictorial essay presents the radiological characteristics of developmental abnormalities and ectopia ...
