Plain-English summary
A 2-year-old Flat-coated Retriever was found to have a mass in the aorta during a CT scan. After a biopsy confirmed it was a type of cancer called chondrosarcoma, the dog received a specialized radiation treatment known as stereotactic body radiation therapy. Initially, the treatment seemed to stabilize the disease for several months, but unfortunately, the cancer progressed later on. Despite the dog's initial good health, it eventually showed signs of multiple organ dysfunction and was euthanized.

Abstract
An intraluminal aortic mass was incidentally found on CT scan in a 2-year-old Flat coated retriever. The mass was larger on repeat CT and was biopsied via right femoral artery catheterisation using endoscopic biopsy forceps. Histopathological examination confirmed an aortic chondrosarcoma. The aortic chondrosarcoma was treated with stereotactic body radiation therapy with 8 Gy delivered in three fractions every other day to a 24 Gy total dose. Follow-up CT 5 months post stereotactic body radiation therapy showed stable disease. No adverse effects secondary to the biopsy procedure or stereotactic body radiation therapy were observed; however, progressive disease was noted 8 months post stereotactic body radiation therapy. The same SBRT protocol was repeated. The dog remained clinically well until presentation 84 days later with signs of multiple organ dysfunction syndrome and was subsequently euthanised.
