Summary
Fine needle aspiration (FNA) biopsy is a reliable method for evaluating thyroid nodules. Ultrasonography, particularly identifying microcalcifications, significantly predicts malignancy risk in thyroid nodules.
Area of Science:
- Endocrinology
- Oncology
- Diagnostic Imaging
Background:
- Thyroid nodules are common, and accurate diagnosis is crucial for patient management.
- Fine needle aspiration (FNA) biopsy is a primary diagnostic tool, often complemented by ultrasonography.
Purpose of the Study:
- To characterize thyroid nodules using FNA biopsy and ultrasonography.
- To assess the diagnostic performance of FNA and identify ultrasonographic predictors of malignancy.
Main Methods:
- Retrospective analysis of 1,004 thyroid nodule FNAs (2000-2007).
- Review of surgical records for 101 patients.
- Calculation of Odds ratios for nodule characteristics and malignancy risk.
Main Results:
- FNA demonstrated high diagnostic accuracy (90.5%) with sensitivity (66.7%) and specificity (95.2%).
- Solitary nodules, irregular margins, and microcalcifications were significant predictors of malignancy (ORs > 3.6).
- Macrocalcification, age, gender, and thyroid status did not correlate with increased malignancy risk.
Conclusions:
- FNA biopsy is a dependable and valid method for thyroid nodule evaluation.
- Ultrasonographic microcalcifications are a critical indicator of malignancy in thyroid nodules.

01:27Goiter
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...
01:23The Thyroid Gland
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...

01:25Hyperthyroidism I: Introduction
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
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 receptors...
01:28Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
01:20Synthesis and Regulation of Thyroid Hormones
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 iodine is then...
