1.5y MC Labrador Retriever mix found recumbent with pale mucous membranes. On unenhanced images, there is a moderate amount of
effusion in the dependent portion of the abdomen (a: asterisk). A hypoattenuating, irregular, linear separation of the splenic capsule and
parenchyma is visible (a: arrow). On arterial phase (b: arrow) and venous phase (c: arrow) images, the region is nonenhancing. The
splenic vein to this region is smaller (d: open arrow) than a neighboring intraparenchymal vessel (e: open arrow) on late‐phase venous
images. Reproduced with permission from S Specchi and K Alexander, University of Montreal, Montreal, Canada, 2014.
