Plain-English summary
A 7-year-old neutered male Labrador Retriever was brought in because of a rapidly growing mass on the right side of his chest that had been present for a month. A CT scan showed that the mass was likely a chondrosarcoma, which is a type of bone cancer, affecting the ninth rib and nearby muscle. The vet removed the mass along with parts of the eighth, ninth, and tenth ribs, using a new surgical technique to help reconstruct the chest wall. The dog recovered well from the surgery and had a good quality of life for six months before being euthanized due to the progression of his underlying disease.

Abstract
CASE DESCRIPTION: A 7-year-old 35-kg (77-lb) neutered male Labrador Retriever was evaluated because of a 1-month history of a rapidly growing mass associated with the right caudal aspect of the thoracic wall. CLINICAL FINDINGS: CT examination revealed an aggressive, osteolytic mass lesion centered around the ventral aspect of the right ninth rib with osteolysis of that rib and focal invasion into the right external abdominal oblique muscle. Preoperative cytologic and histologic findings were most consistent with a chondrosarcoma. TREATMENT AND OUTCOME: The mass and the eighth, ninth, and tenth ribs were resected, and thoracic wall reconstruction was performed with a novel surgical technique involving lateralization of the diaphragm. The dog recovered rapidly and without complications other than a small seroma; no paradoxical chest movement developed, and the cosmetic outcome was good. An excellent quality of life was reported after surgery until the dog was euthanized because of underlying disease progression 6 months later. CLINICAL RELEVANCE: Diaphragmatic lateralization was a simple method of caudal thoracic wall reconstruction that had good clinical results in this case. Research is needed to further assess the safety, reliability, and potential complications of this procedure in dogs.
