Abstract
A 9-year-old female spayed boxer presented for a dorsal cranial mass. Cytology diagnosed a sarcoma. Contrast-enhanced computed tomography (CT) of the head revealed a symmetrical, soft tissue attenuating mass with subtle mineralization and a contrast-enhancing capsule at the dorsal calvarium. There was adjacent frontal bone lysis and contrast enhancement of the parietal lobe. This supported a sarcoma of bone or cartilage origin. Postmortem examination additionally revealed a pulmonary tumor embolus. A final diagnosis of grade III multilobular osteochondrosarcoma (MLO) was made. This is the first study describing a poorly mineralized, encapsulated MLO in a dog and supports a periosteal origin.
