Hemangiosarcoma is a highly malignant neoplasia derived from the endothelial cell line and, therefore, can arise in any tissue with blood vessels. A case of a rare meningeal site of hemangiosarcoma in an eight-year old German Shepherd dog with clinical signs of cauda equina sindrome is described. The diagnosis was made based on clinical, radiographic, tomographic and histopathological findings.
