This week’s case is an Australian Cattle Dog with a history of an oral mass. What are your findings?
Thorax: There are multiple, mineral opacity nodules throughout the pulmonary parenchyma. These are variable in size and shape with irregular margins. The cardiovascular structures appear normal. No abnormalities are noted in the pleural space or mediastinum. The musculoskeletal structures are normal.
Pelvic limbs: On the left fibula, there are two broad based mineral opacity nodules on the medial surface. The remainder of the left pelvic limb, and the right pelvic limb, are normal.
Metastatic osteosarcoma to the thorax and skeleton from the primary oral mass.
