Summary
This case report details the first known instance of thyroid storm (TS) in a dog, caused by a functional thyroid carcinoma. The study outlines the severe clinical signs, progression, and challenges in managing this rare and critical condition.
Area of Science:
- Veterinary Medicine
- Endocrinology
- Oncology
Background:
- Thyroid storm (TS) is a life-threatening condition characterized by exaggerated signs of thyrotoxicosis.
- Functional thyroid carcinoma can lead to excessive thyroid hormone production.
Observation:
- A 12-year-old Golden Retriever presented with severe weight loss, hyperthermia, and tachycardia.
- A ventral neck mass and significantly elevated thyroxine levels were noted.
- Cervical ultrasound revealed a suspected thyroid mass invading the jugular vein.
Findings:
- Despite aggressive treatment, the dog's condition progressed to clinical thyroid storm.
- Postmortem examination confirmed the clinical diagnosis of thyroid storm secondary to thyroid carcinoma.
Implications:
- This is the first reported case of thyroid storm in a canine patient.
- Highlights the potential for functional thyroid carcinoma to precipitate thyroid storm in dogs.
- Underscores the critical nature and diagnostic challenges of this condition in veterinary medicine.

01:23The Thyroid Gland
5.4K
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...

01:20Synthesis and Regulation of Thyroid Hormones
6.1K
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...

2.4K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

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...

404
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
