Abstract

11-year-old neutered male dog was presented with paralysis with decreased postural reaction in the bilateral pelvic limbs. On MRI and CT, the spinal cord from T13 had a slightly swollen area and lost the central canal. A well circumscribed mass was observed at anterior of a right kidney and invaded the spinal canal through the pleura without the fusion and destruction of the spines. Hemilaminectomy was performed to identify the mass pathohistologically and decompress the spinal cord. The mass was diagnosed as hemangiosarcoma. The dog had showed neither progressive neurologic disorders nor improvement and passed away 58 days after the surgery.

후구마비를 나타낸 11세 숫컷 웰시코기가 내원하였다. 신경검사상 양측 뒷다리는 자세반응이 감소되었으며, 그 밖의 이상소견은 확인되지 않았다. MRI 및 CT 영상에서는 T11-12부위에서 척수 부종 소견을 나타내었으며, 폐의 우측 후엽에 종괴가 관찰되었으며, 종괴는 흉막을 통해 척주관으로 침입되어 있었다. 확정진단 및 척수의 감압을 위해 hemilaminectomy를 실시하였다. 종괴는 혈관육종으로 진단되었다. 종괴 제거후 임상증상의 개선은 확인되지 않았으며, 수술후 58일 후에 폐수종으로 인하여 폐사하였다.
