Summary
Triple ectopic thyroid, a rare developmental anomaly, was identified using SPECT/CT imaging. This advanced imaging revealed multiple thyroid tissue locations when standard scans showed only one, aiding diagnosis.
Area of Science:
- Endocrinology
- Embryology
- Radiology
Background:
- Ectopic thyroid tissue results from developmental errors during the thyroid gland's descent.
- Accurate localization is crucial for managing patients with ectopic thyroid tissue.
- Ectopic thyroid without a normally located gland is uncommon.
Observation:
- A rare case of triple ectopic thyroid tissue was observed.
- Initial planar imaging (Tc-sodium pertechnetate) suggested a single ectopic thyroid site.
- SPECT/CT imaging provided a more detailed and accurate localization.
Findings:
- SPECT/CT imaging successfully identified multiple ectopic thyroid tissue locations.
- This case highlights the limitations of planar imaging for complex ectopic thyroid presentations.
- The absence of normal thyroid tissue in the gland's usual location was confirmed.
Implications:
- SPECT/CT is valuable for characterizing complex ectopic thyroid disease.
- Improved diagnostic accuracy can lead to better patient management strategies.
- This case adds to the limited literature on multiple ectopic thyroid sites without a normal gland.

01:23The Thyroid Gland
6.9K
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...

01:06Scalar and Vector Triple Products
4.4K
Two vectors can be multiplied using a scalar product or a vector product. The resultant of a scalar product is scalar, while with vector products, the resultant is a vector. These rules of the scalar or vector product between two vectors can be applied to multiple vectors to obtain meaningful combinations. The scalar triple product is the dot product of a vector with the cross product of two vectors.

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:20Synthesis and Regulation of Thyroid Hormones
7.4K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
