Soft tissue ultrasound corresponding to the site of the palpable bony protuberance confirms a bifid rib within the right anterolateral thoracic cage. The rib is easily followed along its course to bifurcate or fork at its sternal end. The exact rib may be difficult to confirm sonographically, especially in a pediatric patient, and dedicated chest and rib views can be utilised to confirm this sonographic finding and to exclude other occult pathology.
