Abstract
Elbow hygroma and hypertrophic osteodystrophy were diagnosed in Doberman referred to Veterinary Teaching Hosptial of Chungbuk national University. Physical examination, plain radiography, and bone scan were performed in the patient. The radiography revealed soft tissue swelling on the caudal region of the elbow and irregular radiolucent zone involving the metaphysis subjacent and parallel to the distal radial and ulnar physes. The bone scan of the forelimbs revealed increased uptake in region where the soft, fluid-filled mass on the elbow was present. But the radiolucent areas (the distal radial and ulnar physes) were seen normal bone uptake. Therefore, hypertrophic osteodystrophy ruled out the diagnosis. $^{99m}Tc-MDP$ scan is suitable to routine clinical use for soft tissue inflammation and bone lesions detection.
