Assessing the Diagnostic Accuracy of TI-RADS in Pediatric Thyroid Nodules: A Multi-institutional Review

jpedsurg.org

Thyroid nodules are uncommon in children and adolescents but carry an increased risk of malignancy when present. The Thyroid Imaging Reporting and Data System (TI-RADS) is an adult-validated ultrasound-based risk assessment providing a prediction of malignant potential for thyroid nodules, thereby guiding recommendations for fine needle aspiration biopsy (FNAB). Minimal data exist regarding the applicability of TI-RADS to predict malignancy in pediatric thyroid nodules. This study aims to analyze the performance of TI-RADS for children and adolescents with thyroid nodules, hypothesizing that applying TI-RADS criteria would improve accuracy and reduce the number of recommended FNAB compared to American Thyroid Association (ATA) size criteria alone.

In brief

This multi-institutional study evaluates whether the adult-validated TI-RADS ultrasound scoring system accurately predicts malignancy risk in pediatric thyroid nodules and could reduce unnecessary biopsies compared to current ATA size-based guidelines. Given the higher malignancy rate of thyroid nodules in children, improved risk stratification tools are clinically important for this population.

Thyroid nodules are rare in pediatric patients but have higher malignancy risk than in adults.
TI-RADS is validated for adults but lacks robust pediatric data for predicting thyroid malignancy.
Study evaluates whether TI-RADS improves diagnostic accuracy over ATA size criteria in children.
Goal is to reduce unnecessary FNABs while maintaining detection of malignant pediatric thyroid nodules.
