The possibility of intrathyroid ectopic thymus should be considered when a mid- to low-lying intrathyroid lesion with a fusiform shape with multiple linear or punctate internal echoes is detected on US in children.

This study suggests that excluding increased vascularity and adding solid composition to the suspicious ultrasonographic features of the ATA guidelines would significantly improve the diagnostic performance in subcentimeter nodules for the identification of malignant lesions.
