Plain-English summary
A 10-year-old female mixed breed dog with a lung tumor caused by osteosarcoma (a type of bone cancer) underwent a procedure called video-assisted microwave ablation (VAMA) to treat the metastatic lung lesion. Before this, she had her leg amputated and received chemotherapy. After the VAMA procedure, her symptoms related to hypertrophic osteopathy (a bone condition) improved, and follow-up X-rays showed the lung tumor was stable. Unfortunately, about four months later, she developed lethargy and breathing problems and sadly passed away shortly after being taken to an emergency clinic.

Abstract
OBJECTIVE: To describe video-assisted microwave ablation (VAMA) for the treatment of a metastatic lung lesion secondary to right forelimb osteosarcoma in a dog. STUDY DESIGN: Case report. ANIMALS: A 10-year-old female spayed mixed breed dog with a metastatic lung lesion secondary to appendicular osteosarcoma. METHODS: An osteosarcoma of the right distal scapula and proximal humerus that was suspected to be a radiation-induced osteosarcoma was treated with limb amputation and carboplatin chemotherapy. The patient developed pulmonary metastatic lesions and hypertrophic osteopathy (HO). VAMA of a metastatic lesion in the right caudal lung lobe was performed 227 days after amputation. The procedure was performed without complication. RESULTS: Follow-up information with the referring veterinarian 40 days after VAMA indicated that the patient was stable and that the clinical signs of HO had resolved. Thoracic radiographs taken by the referring veterinarian (RDVM) at monthly intervals showed that the previously treated metastatic lesion was stable. At 134 days from VAMA, the patient presented to the RDVM for lethargy and dyspnea and was transferred to an emergency clinic. The patient arrested and died 136 days from the VAMA procedure while hospitalized. A postmortem was not performed. CONCLUSION: VAMA for pulmonary metastatic lesions is technically feasible and allows for the treatment of symptoms associated with HO and minimally invasive management of pulmonary metastases in the case reported.
