Summary
Thyroid nodules are common in adults. Increased use of ultrasonography has revealed a higher prevalence of clinically inapparent thyroid nodules in the general population.
Area of Science:
- Endocrinology
- Radiology
Background:
- Thyroid nodules are a common finding in the adult population.
- Palpation estimates suggest a prevalence of 3% to 7% for thyroid nodules.
- Widespread use of ultrasonography (US) has increased the detection of clinically inapparent thyroid nodules.
Purpose of the Study:
- To review the prevalence and detection of thyroid nodules.
- To highlight the impact of ultrasonography on diagnosing thyroid nodules.
Main Methods:
- Literature review on thyroid nodule prevalence.
- Analysis of data from ultrasonography studies.
Main Results:
- Thyroid nodule prevalence is estimated between 3% and 7% based on palpation.
- Ultrasonography reveals a significantly higher prevalence of thyroid nodules, ranging from 20% to 76% in the general population.
- The increased prevalence is attributed to the widespread use of US for neck imaging.
Conclusions:
- Thyroid nodules are highly prevalent in the adult population.
- Ultrasonography has dramatically increased the detection rate of thyroid nodules, particularly those not clinically apparent.
- Current diagnostic approaches should consider the high prevalence revealed by imaging techniques.
