Patchy increased medullary bone opacity in left and right radius and possibly in proximal left and right ulna.
Endplate lysis and irregular active periosteal proliferation involving multiple sternal segments.
Aggressive bone lesions involving both antebrachia and multiple sternal segments.
Antebrachial lesions are consistent with canine panosteitis but sternal changes are not.
