Sternal Pseudotumor of Childhood

The common approach to rapidly growing peristernal lesions in young infants is oncologic consultation, imaging, and early tissue diagnosis. We represent 3 such cases with unique sonographic findings favoring nonaggressive lesions named self‐limiting sternal tumors of childhood, in which a conservative approach of sonographic follow‐up was chosen. We review the typical sonographic characteristics in this rather new and rare entity, separating it from the more aggressive group of lesions in this location and age group, and suggest that the classic appearance should imply a wait‐and‐see approach, with sonographic follow‐up studies rather than invasive intervention.
