This case is an 8 year old female neutered Golden Retriever with 5-week history of lameness. How would you describe the lesion?
4 Views provided of the distal left limb focused on the carpus. Views include a mediolateral, Dorsopalmer , a DL-PaMO (top right) and a DM-PaLO (last image). The exposure and positioning is good.
There is diffuse, ill-defined heterogenic opacity, however dominated by radiolucency within the distal radius. There is cortical bone destruction with associated irregular periosteal reaction predominately over the dorsomedial aspect of the distal radius. There is a marked increase in soft tissue opacity around the distal radius and carpus joints.
There is mild enthesophyte development along the proximal aspect of metacarpal 2 and to a smaller degree the palmar aspect of the accessory carpal bone.
Radiographic Diagnosis: Primary Bone Tumour
Differentials: Osteomyelitis and less likely metastatic bone neoplasia
Additional standard 3-views thoracic radiographs are required to further stage this patient, which could be improved by the use of CT or MRI studies.
