Abstract

Inflammatory sinonasal disease was diagnosed in five dogs and two cats with clinical signs of nasal discharge and epistaxis. Survey radiography and CT were performed in all of patients. CT scan of the rostral cranium was performed with a thickness of 2 or 5 mm. Nasal cytology and culture from nasal smear were performed immediately after CT examination. Remarkable increase of opacity in the nasal cavities and frontal sinuses was observed in only 3 cases. On CT images, the cavitating lesions were isodense in nasal cavity (7 cases), frontal sinuses (3 cases), and nasopharynx (2 cases) with destruction of the nasal septum (4 cases), maxillary turbinates (5 cases), maxilla (3 cases), and hard palate (3 cases). The lesions were enhanced after intravenous contrast administration in 5 cases and were not enhanced in 2 cases. Inflammatory cells were observed in nasal cytology. Most of the cultures from nasal smear were bacteria. CT is useful to diagnose sinonasal disease and is more accurate in demonstrating the extent and character of lesions of nasal cavity than radiography.

만성의 비강 삼출물 및 비출혈로 내원한 5마리의 개와 2마리의 고양이가 내원하여 일반 방사선 검사 및 컴퓨터단층촬영 (CT), 비강의 세포학적 검사와 미생물학적 검사를 실시하여 비염으로 진단한 증례를 선정하여 이의 CT 영상의 특징을 비교 평가하였다. 비강의 일반 방사선 검사에서 3 증례에서만 비강의 비정상 소견을 확인하였다. CT 검사 결과, 비강 (7증례) 및 전두동 (3 증례), 비인두 (2증례)에서 공동을 갖는 isodense한 병변을 확인하였으며 비중격의 소실 (4 증례), 비갑개의 파괴 (5 증례), 상악 (3 증례) 또는 경구개 (3 증례)의 골융해 소견이 관찰되었다. 병변의 조영증강효과는 5 증례에서 확인하였다. CT는 비강의 질병을 평가하고 특히 병변의 범위를 결정하는데 매우 유용하다.
