Spinal cord injuries often occur in small animals due to exogenous or endogenous causes. Spinal cord injury is classified into extradural, intradural-extramedullary and intramedullary. This study aims to determine the lesions involving the spinal cord and its findings and different frequencies to myelography. At the same time, another study with six patients with inconclusive examinations to myelography underwent computed tomography contrasting and their findings were compared with myelography. In this study were reassessed 154 cases of dogs with neurological clinical suspicion surrounding the spinal cord, which underwent conventional radiographs and myelography with nonionic iodinated compound in the period 2008 to 2012. The imaging studies were developed in Sector Diagnostic Imaging Veterinary Hospital Governador Laudo Natel of the Faculdade de Ciências Agrárias e Veterinárias Jaboticabal - Unesp. Among the different breeds of dogs, the Teckel were the most affected with the presentation of 58 patients (38%). The age group most frequent was 5-8 years, totaling 67 dogs (43.5%). The cervical column was the most frequent segment of the lesions found in 88 lesions (44%). The most common location of lesions was extradural corresponding to lesions of the total analyzed 191 (95.5%) and nine lesions were intradural extramedullary (4.5%). Extradural lesions of 175 (91.6%) were degenerative intervertebral disc protrusion / extrusion. Aside from the 154 cases in the first half of 2013, in six other patients were performed sequentially myelography and computed tomography. In these cases the lesions were in the neck: three cases (50%), two in the lower back (33%) and one thoracolumbar (17%). All lesions were extradural three cases of disc extrusion (50%), two protrusion (33.3%) and one for cancer/osteomyelitis (16.7%). The myelography permits, in most cases lead to a definitive diagnosis in patients with spinal cord compression injury. Computed ...
