Abstract

A 7-year-old, male Alaskan malamute was referred for a routine dental management. On the physical examination, 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 second lumbar vertebra. The cyst showed hypointense on a T1-weighted image with rim enhancement and hyperintense on a T2-weighted image. The cystic lesion was removed through right-side hemilaminectomy. In the histopathological examination, evenly distributed fibroblasts and collagenous stroma with several cartilaginous materials were seen. The neurological signs of the right hindlimb were successfully recovered within a week in follow-up neurological examination and showed normal gait at 6 months after surgery.

7년령 수컷 말라뮤트 견이 정기적인 치과진료를 목적으로 내원하였다. 신체검사 상에서 뒷다리의 운동 실조가 확인되었으며, 우측 뒷다리의 고유 자세반응이 미약하게 지연되었다. 감별진단을 위한 MRI 검사에서, 허리뼈 1번과 2번 사이 척수강에 경막외 낭종이 확인되었다. 낭종은 디스크 바로 등쪽에서 척수실질 배쪽을 등쪽으로 심하게 압박하고 있었으며, T1 저신호, T2 고신호 및 낭종 벽을 따라 조영증강이 확인되었다. 편측성 추궁절제술을 통해 낭종을 제거하였고, 조직검사 결과 낭종의 벽은 섬유소 및 섬유아세포가 혼재되어 있었으며 일부분에서 호염성 디스크 물질이 확인되어 디스크 낭종으로 진단하였다. 환자는 수술 후 신경증상은 정상적으로 회복하였으며, 6개월 후 신체검사에서 정상적인 보행 이 관찰되었다.
