The Management of Thyroid Nodules

Area of Science:

• Endocrinology
• Diagnostic Imaging
• Pathology

Background:

• Thyroid nodules are highly prevalent, detected in 3-7% by palpation and 70% by ultrasonography (USG).
• Approximately 5-15% of thyroid nodules are malignant, necessitating accurate detection methods.

Purpose of the Study:

• To outline the primary aims and common diagnostic methods for thyroid nodule examination.
• To discuss the challenges in diagnosing nodules with indeterminate fine-needle aspiration biopsy (FNAB) results.

Main Methods:

• Medical history and physical examination.
• Ultrasonography (USG) and ultrasound-guided fine-needle aspiration biopsy (FNAB).
• On-site assessment of FNA specimens to reduce non-diagnostic results.

Main Results:

• USG and FNAB are standard diagnostic tools for thyroid nodules.
• Ultrasound-guided FNAB with on-site assessment improves diagnostic accuracy.
• The "atypia of undetermined significance" category presents diagnostic challenges.

Conclusions:

• Accurate detection of malignant thyroid nodules is crucial.
• Developing methods like molecular markers and elastography are under investigation for indeterminate cases.
• Current routine examination relies on established USG and FNAB techniques due to cost-benefit considerations.
