Figure 3.

(a–d) Normal appearance of the spleen in four cats. In each example, the spleen (short arrows) appears as an elongated organ with fine echotexture within the near field of the image due to its superficial location within the abdomen. (b) The echogenic capsule surrounding the spleen is particularly conspicuous. (c) Splenic veins (long arrows) are visible within the hilar region of the spleen. (d) Marked thickening of the muscularis layer of the ileum (long arrow) is visible, and is surrounded by hyperechoic reactive fat. Two videos showing the appearance of a healthy spleen in a kitten are available as supplementary material
