A 7-year-old, male Alaskan malamute was referred for a routine dental management. On the physicalexamination, the right hindlimb ataxia with a mild delay in proprioception was noted. On magnetic resonance images,an extradural ventral cystic structure compressing the spinal cord was found at the level between the first and secondlumbar vertebra. The cyst showed hypointense on a T1-weighted image with rim enhancement and hyperintense ona T2-weighted image. The cystic lesion was removed through right-side hemilaminectomy. In the histopathologicalexamination, evenly distributed fibroblasts and collagenous stroma with several cartilaginous materials were seen. Theneurological signs of the right hindlimb were successfully recovered within a week in follow-up neurologicalexamination and showed normal gait at 6 months after surgery.
