Atypically located accessory splenic hemangiosarcoma in a Dog: Diagnostic value of triple-phase computed tomography

초록

A 10-year-old Cocker spaniel presented with lethargy. Triple-phase computed tomography was obtained with a contrast test bolus at the level of porta hepatis, which revealed a right lower abdominal mass. The mass was not connected to other abdominal organs; however, a linear structure was observed connecting the splenic hilum to the mass, which was suspected to be the feeding vessel. The arterial phase image was obtained again with a contrast bolus at the level of the celiac artery. A prominent contrast-enhanced feeding artery originating from the splenic artery to the mass was observed. Histopathology confirmed an accessory splenic hemangiosarcoma. Graphical Abstract: In a 10-year-old Cocker spaniel, an ultrasound revealed a right caudal abdominal mass. On triple-phase CT, the mass was not connected to adjacent organs, but feeding vessels from the spleen connecting to the right caudal abdominal mass were observed. The right caudal mass was suspected to be an accessory splenic mass, and it was confirmed as accessory splenic hemangiosarcoma supplied by the feeding vessels from the spleen on the histopathology. image
