Plain-English summary
A 12-year-old male cat was brought to the vet because he was feeling depressed and having trouble breathing. X-rays and a CT scan showed fluid in his chest and solid masses in his bones. Sadly, the cat passed away just two days later, and a postmortem exam revealed lung cancer that had spread to his bones. This case is notable because it is the first reported instance of this type of bone metastasis in cats.

Abstract
A 12-year-old male cat with depression and dyspnoea was presented for investigation. Radiography and computed tomography revealed hydrothorax and solid masses involving the sternum, ribs and thoracic vertebrae. The cat died two days after first presentation, and postmortem examination revealed lung masses and proliferative bony lesions. Histologically, a neoplastic proliferation of epithelial cells was seen in the lungs, with a large amount of collagen and deposits of cholesterin. The bone lesions were also composed of neoplastic epithelial cells and abundant calcified osteoid, without atypia. A diagnosis of pulmonary adenocarcinoma with osteoblastic bone metastases was made. This is the first reported case of osteoblastic metastases in the cat.
