Five dogs were presented to CGS hospital, Gurgaon with the history of limping on the right forelimb (3), Left forelimb (1) and left hind limb (1). Neurological examination, haematology, and routine survey radiography were done. Computed Tomography (CT) under gaseous anesthesia was done to enable further diagnosis. CT scan revealed osteolysis of the left distal radius (1), proximal right humerus (3) and left distal femur (1). Columnar periosteal reaction with new bone formation and cortical thinning was seen in two cases. Biopsy of the proximal right humerus (3) revealed osteosarcoma in two cases and inconclusive in one case. CT scan diagnosis is beneficial in metastasis checks, surgical planning and the relation of lesion with the surrounding tissue.
