Abstract
We report a case of a 12-year-old intact male Welsh Corgi which was referred to our institution for epistaxis. Computed tomography (CT) imaging revealed a mass in the left nasal cavity. The mass was diagnosed as a hemangiosarcoma on the basis of histopathological analysis. The dog was treated with chemoradiotherapy. CT imaging performed at the 124th day after the first visit revealed that the size of the mass had decreased. However, a CT scan at the 208th day demonstrated recurrence, and pulmonary metastasis was identified by a CT scan at the 271st day. The treatment continued at another hospital; however, the dog died at the 331st day. Dogs with hemangiosarcomas in the nasal cavity may respond better to chemoradiotherapy and survive longer than dogs with hemangiosarcomas in the spleen or heart.
