Disk injuries are most common between a T11-L12 inter spaces. A syndrome is observed frequently in chondrodistrophic and small races, such as Dachshound, Beagle, Caniche, Shitzu and Maltese. It is classificated by veterinarians in two types of disk degenerations: they are Hansen type I and type II protrusions. Objective. To introduce a new method that allows a diagnosis of a canine disk disease by the use of magnetic resonance. Materials and methods. A magnetic resonance was used by veterinarians for a final diagnosis in a disk injury in a Beagle that also had a disease related with a Euthyroid Patient Syndrome. Results. A definite diagnosis of a lumbar herniated disk was confirmed by the use of magnetic resonance. Results of a blood chemical, a thyroid hormone analysis and a patient’s clinic history show a syndrome compatible with that of the euthyroid patient. Conclusion. A magnetic resonance can be a certain method for a definitive diagnosis for disk injuries in small animals.esHernia discalCorporación Universitaria LasallistaSíndrome del paciente eutiroideoEnfermedad discal caninaSobrepesoPerros - EnfermedadesPerrosArticle
