Abstract

Nasal tumors have been reported frequently in dogs and nasal discharge has been the primary presenting complaint in nasal tumor patients. A 10-year-old 7 kg male mixed breed dog was presented to the animal hospital for evaluation of severe bloody nasal discharge. After physical examination, blood examination and X-ray examination, magnetic resonance imaging (MRI) examination was also conducted. Based on MRI nasal tumor which does not extend cranial vault was diagnosed. The nasal tumor was confirmed as adenosquamous cell carcinoma by histopathological examination after necropsy. The invasive characteristics of the neoplasm were documented by MRI. MRI was very valuable diagnostic tool for identifying extracranial and intracranial tumor invasion in a small animal.

10년령의 잡종견이 2개월 전부터 지속적인 기침, 혈액성 비루 및 개구호홉을 주증으로 내원하였으며 혈액검사, 두부 X-ray촬영 및 두부 MRI촬영을 실시한 결과 빈혈소견과 함께 MRI 촬영에서 두개내강으로 파급되지 않은 비강종양으로 추정되는 큰 mass가 비강쪽에서 발견되었다. 그러나 축주의 요청에 의해 이틀 후 안락사하여 부검 후, 병리조직 검사를 실시한 결과 비강 선편평세포암종임을 확인하였다. 본 증례를 통하여 비강종양과 같이 두경부 병변에 있어서 자기공명영상진단법(MRI)은 고전적 방사선학적 검사법에 비교하여 종괴의 침습성과 파급정도를 정확히 평가함으로써 치료방향의 설정과 그 예후를 평가함에 있어 뛰어난 검사법임을 확인할 수 있었다.
