A normal thymic gland in a neonate appears as a well-defined homogeneous hypoechoic soft tissue mass in the superior mediastinum, predominantly right-side, with bulk dimensions of 3.2 x 2.4 cm.
Case Discussion
The thymus is larger in the young pediatric population and regresses with age.
As most very young children have supine projection chest radiographs, this can further contribute to the spurious appearances of a mediastinal mass.
