초록

15년 령의 중성화 수컷 요크셔 테리어가 양측 후지의 보행 장애로 내원하였다. 5개월 전부터 후구 부전마비가 시작되어 점점 진행되었고, 4일 전부터는 증상이 빠르게 악화되었다. 후구 부전마비를 일으킬 수 있는 신경 질환을 감별하기 위해 컴퓨터 단층 촬영과 자기 공명 영상이 실시되었다. 컴퓨터 단층 촬영을 통해 4번 요추의 골 결손과 인접 부위의 연부 조직 종괴를 확인하였다. 자기 공명 영상을 통해서는 4번 요추의 왼쪽에서 T1강조 영상에서의 등신호종괴와 T2강조 영상에서의 고신호 종괴가 척수를 압박하는 것을 확인하였다. T1강조 영상에서 조영제 주입 후 종괴의 신호가 균일하게 증가하였다. 종괴의 절제 후 통증은 완화되었다. 조직병리학적 검사를 통해 병변이 척추 골육종임을 확인하였다. 컴퓨터 단층 촬영과 자기 공명 영상은 개에서 척추 골육종을 진단하고 수술적 제거를 위한 계획을 세우는데 유용하게 이용될 수 있다.

A 15-year-old neutered male Yorkshire terrier was presented with a gait disorder of the pelvic limbs. For differential diagnosis of neural disease, magnetic resonance imaging (MRI) and computed tomography (CT) scan were performed. CT showed bone defect in the 4th lumbar vertebra and adjacent soft tissue mass. MRI revealed a mass in left side of the 4th lumbar vertebra. The mass was uniformly enhanced on contrast-enhanced T1-weighted imaging (T1W1). Excision of the mass alleviated back pain. Vertebral osteosarcoma was identified by the histopathological examination. Therefore, CT and MRI were helpful to diagnose vertebral osteosarcoma in the dog and to plan surgical excision of the mass.
