Summary
Cervical schwannomas can mimic thyroid nodules. Magnetic resonance imaging (MRI) and specialized cytologic stains aid in the preoperative diagnosis of these nerve sheath tumors.
Area of Science:
- Neurology
- Oncology
- Radiology
Background:
- Presents a case of cervical schwannoma, a nerve sheath tumor.
- The lesion mimicked a thyroid nodule, complicating initial diagnosis.
- Origin likely from the pharyngeal plexus of the vagal nerve.
Purpose of the Study:
- To highlight the diagnostic utility of MRI in identifying cervical schwannomas.
- To review radiographic characteristics of nerve sheath tumors on MRI.
- To emphasize the role of cytologic stains in preoperative diagnosis.
Main Methods:
- Case report of a 60-year-old female with dysphagia and a neck mass.
- Analysis of patient history, diagnostic imaging (MRI), cytology, and pathology.
- Utilized MRI for suspected preoperative diagnosis, followed by specialized cytologic stains.
Main Results:
- MRI was instrumental in suspecting a cervical schwannoma.
- Specialized cytologic stains enhanced the possibility of a correct preoperative diagnosis.
- The lesion was confirmed to be a schwannoma.
Conclusions:
- Cervical schwannomas should be considered in the differential diagnosis of thyroid nodules.
- Fine needle aspiration cytology indicating neural cells warrants further investigation for schwannoma.
- MRI is a valuable tool for detecting neural lesions masquerading as thyroid nodules.

The Thyroid Gland
8.0K
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...

Synthesis and Regulation of Thyroid Hormones
8.3K
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...

Functions of Thyroid Hormones

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...
