Hemangiosarcoma can occur in any tissue with blood vessels, and most common sites in dogs are spleen, heart, skin and liver. A14-years-old dog, female, weighting 6 kg showing symptoms of primary cutaneous hemangiosarcoma and nonregenerative anemia without metastic lesions in ultrasonographic and radiographic tests was treated with surgery, chosen by owner. After 4 months, it returned showing ataxia and cerebellar symptoms, which were treated efficiently, but after 15 days, symptoms returned and euthanasia was made. Necroscopic and histologic findings pointed to metastatic cerebellar hemangiosarcoma with focal necrosis diagnosis. Given the very high metastatic rate of most canine hemangiosarcoma and the poor outcome associated with surgery alone, the cerebellus metastic is reported but is uncommon and have poor prognosis.
