Summary
This study reports a rare case of non-functional ectopic thyroid tissue in the neck, distinct from a normal thyroid gland. Diagnosis involved imaging and histology, confirming the ectopic tissue
Area of Science:
- Endocrinology
- Surgical Pathology
- Diagnostic Imaging
Background:
- Ectopic thyroid tissue is a rare congenital anomaly.
- Non-functional ectopic thyroid tissue coexisting with a normal thyroid gland is exceptionally rare.
- Accurate diagnosis is crucial for appropriate management.
Purpose of the Study:
- To document a rare case of non-functional ectopic thyroid tissue in the neck.
- To highlight diagnostic modalities and surgical management.
- To contribute to the literature on thyroid anomalies.
Main Methods:
- Case presentation of a 36-year-old female with an anterior neck mass.
- Diagnostic workup included ultrasonography, computed tomography (CT), and scintigraphy.
- Surgical en bloc resection followed by histological examination.
Main Results:
- Imaging revealed a normal thyroid gland and a separate solid neck mass.
- Scintigraphy showed no uptake in the mass, indicating non-functionality.
- Histology confirmed the mass as ectopic thyroid tissue, well-encapsulated and separate from the native thyroid.
Conclusions:
- Non-functional ectopic thyroid tissue can occur alongside a normal thyroid gland.
- Multimodality imaging is essential for diagnosis.
- Surgical resection is a viable treatment option with good outcomes.

01:25Hyperthyroidism I: Introduction
64
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

01:27Hyperthyroidism II: Pathophysiology
58
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...

01:23The Thyroid Gland
7.1K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:24Graves Disease II: Pathophysiology
59
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...

01:27Goiter
41
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...

01:23Hypothyroidism II: Pathophysiology
58
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
