Abstract

An intact female, 5-year-old, Pekingese, weighing 3.5kg with a history of a palpated abdominal mass was referred to Veterinary Medical Teaching Hospital, Seoul National University. In laboratory examination, there were no remarkable abnormalities. Radiographic findings included a left mid-abdominal mass with ill-defined margin, serosal detail loss of peritoneal space, non-uniform opacity of retroperitoneal space, and a radiopaque cystic calculus. On abdominal ultrasonography, a heterogeneous parenchymal mass with irregular contour in the left renal region was found. Computed tomographic findings showed a tumor embolus within the caudal vena cava and an invasion into mesentery, small bowel loops, spleen and pancreas around the large left renal mass. Unilateral nephroureterectomy was performed. Histopathologic examination of the resected mass confirmed the diagnosis of renal cell carcinoma. The dog died one day after surgery. Although ultrasonography could give diagnostic information about mass characteristics, computed tomography (CT) can provide key imaging features of mass characteristics.

5년령 페키니즈가 촉진가능한 복강종괴 때문에 서울대학교 부속동물병원에 내원하였다. 실험실 검사에서 특별한 이상은 없었다. 방사선 검사에서 경계가 분명한 좌측 복부중간에 종괴가 있고 복강내 장막선 손실, 후복강의 비정형성투명도, 그리고 방사선 불투과성 방광 결석 소견을 나타냈다. 복강초음파에서 좌측신장에 불규칙한 모양을 한 비균질성 실질종괴가 발견되었고 좌측대형신장종괴가 장간막, 소장, 비장, 췌장을 침습한 소견을 관찰하였다. 편측성 신장요관절제술을 실시하였다. 조직병리소견에서 신장세포암종으로 확진하였다. 수술후 다음날 환축은 폐사하였다. 비록 초음파검사로 종괴에 관한 진단적 정보를 알 수 있지만, 컴퓨터 단층촬영은 종괴의 특성에 관한 핵심 영상 소견을 나타낸다
