Insights into Ultrasound Features and Risk Stratification Systems in Pediatric Patients with Thyroid Nodules

Area of Science:

• Pediatric Endocrinology
• Radiology
• Oncology

Background:

• Thyroid nodules are less frequent in children than adults but carry a higher risk of malignancy.
• Current ultrasound risk stratification systems (RSSs) are primarily developed for adults and lack validation in pediatric populations.
• Accurate risk assessment is crucial for managing pediatric thyroid nodules, given their higher malignancy potential.

Purpose of the Study:

• To evaluate available data on ultrasound (US) features of thyroid nodules in pediatric patients.
• To summarize evidence on the performance of US risk stratification systems (RSSs) in predicting malignancy in pediatric thyroid nodules.
• To provide insights into the clinical management of thyroid nodules in the pediatric population.

Main Methods:

• Systematic review of existing literature on pediatric thyroid nodules.
• Analysis of studies reporting on ultrasound features and their association with malignancy risk.
• Evaluation of the performance of adult-derived RSSs when applied to pediatric cases.

Main Results:

• Pediatric thyroid nodules exhibit distinct US characteristics compared to adults.
• The efficacy of adult-based RSSs in pediatric patients requires further validation.
• Higher malignancy rates underscore the need for specialized diagnostic approaches in children.

Conclusions:

• Further research is needed to validate and potentially adapt RSSs for pediatric thyroid nodule evaluation.
• Standardized US criteria and risk stratification are essential for optimizing the management of pediatric thyroid nodules.
• Early and accurate diagnosis is critical to guide appropriate treatment and improve outcomes for children with thyroid nodules.
