Abstract

Three dogs having adrenal masses detected on ultrasonographic examination were underwent computed tomography (CT) for surgery. After adrenalectomy, each mass was diagnosed pheochromocytoma with myelolipoma, adrenocortical carcinoma and adrenal adenoma through histopathology. Five minutes were used to get delayed enhanced CT images. Attenuation value was measured in each mass and the absolute and relative percentage of enhancement washout were calculated.

복부 초음파 영상검사에서 부신 종괴가 확인된 세 마리의 개에서 지연형 조영증강 전산화단층촬영을 적용한 영상검사가 진행되었다. 조영제 주입 전과 주입 직후, 5분의 지연 시간 후에 CT 검사를 하였으며 위치, 조영 전과 후의 양상, 주변 장기와의 관계, washout 정도를 평가하였다. 세 마리 개 모두에서 부신절제술이 실시되었으며 조직병리 검사 결과 골수지방종을 동반한 크롬친화세포종, 부신샘종, 부신암종으로 진단되었다. 부신암종을 가진 한 마리의 개를 제외하고는 수술 후 회복하여 퇴원하였다.
