Diagnosis of neurologic compression of the spinal cord of dogs with use of Helical Computed Tomography (CT)

Neurological disorders in dogs are common in veterinary medical practice routine, being necessary to identify the site of injury in the event of compression on structures of the central nervous system (CNS). The aim of this work was an epidemiological study of neurological changes in compressive spinal cord of pet dogs in Salvador and the metropolitan area. Discopathies, neoplasms and trauma were identified by Computed Tomography (CT). We evaluated 17 dogs of various breeds, aged between 2 and 10 years old and of both sexes, from two veterinary medical routine services and forwarded to the examination as clinically indicated. Slice images with a thickness ranging from 0.5 to 2mm were produced in rotation with the tomograph. Animals that showed disc disease (70.58%) for extradural myelopathy 6/12 (50%) were the breed Dachshund, mean age 7.33±1.97 years and for all other occurrence was timely; 23.53% of vertebral bone disease, bone tumors and fractures, and 5.89% corresponding to neoplasm marrow. There was a higher incidence of injuries segments L2-L3 (25%), followed by C4-C6 (16.67%), T12-T13 (16.67%), L7-S1 (16.67%) of cases.
