Since there is a protruding rib on the right side by ultrasonography
the doctor would be interested in knowing whether there is any abnormal mass or growth below the rib also the status of the liver
and lungs below it.
Would like to know whether calcium studies were done because rickets
can lead to protrusion of ribs.
Also if there is any pain at the site because osteochondritis
can also lead to pain with swelling in the rib.
At present one will have to wait for the reports to confirm that the problem is only external and not originating from internal organs.
