Abstract
A 7-year-old intact female dachshund (Dog 1) and a 17-year-old intact male Yorkshire terrier (Dog 2) were presented for evaluation of mammary gland tumor and a regular checkup, respectively. Incidentally, segmental caudal vena cava aplasia was detected on CT images in both dogs. Absent postrenal segment (Dog 1) or discontinuation of caudal vena cava (Dog 2) were detected, but prerenal segment of caudal vena cava was continued to the dilated azygos vein. Segmental CVC aplasia should be considered when an abdominal vascular anomaly was evaluated with CT angiography in dogs.
