Chiari-like malformation is a condition characterized by a mismatch in volume between the caudal cranial fossa, which is too small, and the brain, too big, leading to foramen magnum obstruction and secondary syringomyelia - fluid filled cavities within the spinal cord parenchyma. The aim of the paper was to describe and to discuss the Chiari-likemalformation and syringomyelia magnetic resonance imaging characteristics, to asses the extension and severity of the neurological lesions. This research presents a retrospective study on 46 dogs, during the period 2013-2017. All dogs were subjected to magnetic resonance imaging examination; T1- and T2-weighted transverse and sagittal images of the brain, craniocervical junction and cervical spine were obtained in all cases. Each patient was assigned a grading of Chiari-like malformation and syringomyelia, according to the British Veterinary Association/Kennel Club-Chiari-like malformation and Syringomyelia Health Scheme. Chiari-like malformation and syringomyelia were shown in all cases, and although the clinical symptoms, the breed and history generates a presumptive diagnosis, the diagnosis can only be confirmed by magnetic resonance imaging examination.
