dc.description.abstractIntroduction Osteosarcoma (OSA) is the most common primary bone tumor in dogs. Between 20 and 25% of canine OSA arise from bones of the axial skeleton and are also the most common extradural spinal neoplasm (46%). Radiographic appearance is nonspecific and inconsistent. Pain without neurological signs is the predominant initial finding with vertebral OSA. Materials and Methods A 8 years cross-bred male dog was presented for consultation complaining of progressive weight loss, apathy and nonspecific pain. A paralumbar mass on the left side was diagnosed after clinical and radiographical examination. Cytology of the mass was performed and the animal was hospitalized for pain control and nutritional support until definitive diagnosis. During hospitalization, the clinical status of the animal deteriorated emerging neurological abnormalities. The cytology revealed the presence of cells characteristic of a neoplastic process of mesenchymal origin, apparently sarcoma. It was decided to perform a myelogram wich revealed spinal cord compression at L4, caused by the mass. Due to the deterioration of clinical status and the diagnosis owners decided for euthanasia. Results At necropsy was observedthe thickening of the transverse process of L4 vertebra by a mass with 6.3 x 7.0 x 4.5 cm. The histopathological diagnosis revealed an OSA with different histologic aspects. Discussion and Conclusion An unsucessful outcome OSA was diagnosed. Aadequately treatinglocal disease ofvertebral OSA is very difficult. Surgery is an attempt to decompress dogs with neurologic deficits or intractable pain. Present recommendations are to perform surgery for decompression and institute radiation and chemotherapy.por
