Figure 23.3 Lateral image (a) of the abdomen in a cat with hepatomegaly. The caudal liver margins extend well beyond the costal
arch (arrow), and the gastric axis is displaced slightly caudal and dorsal. A moderate volume of peritoneal effusion results in decreased
abdominal detail. Ventrodorsal image (b) of the abdomen in a cat with hepatomegaly. The liver margins extend caudally, and there is
caudal displacement of the gas-filled stomach. Lymphoma was diagnosed on a fine needle aspirate of the liver, a GI mass, and
mesenteric lymph nodes.

Figure 23.4 Lateral (a) and VD (b) images of the abdomen in a normal geriatric cat. (a) The liver extends well beyond the costal arch,
but is sharply marginated and normal in shape. This apparent hepatomegaly is common in geriatric cats, and is due to stretching of
the ligaments supporting the liver against the diaphragm. The liver will “sag” and extend beyond the costal arch. (b) Abundant
peritoneal fat helps to outline the caudal liver margins (arrows).
