Figure 22.8 Ultrasonography of gastric neoplasia. (a) The gastric wall of the cat in Figure 22.7a measured 1.33 cm between the
calipers. (b) In another plane, the gastric wall of the cat in (a) measured 1.94 cm. The wall has mixed echogenicity, appearing
hypoechoic in some areas and hyperechoic in others. Wall layers are not discernible. Enlarged rounded lymph nodes (LN) are seen
adjacent to the stomach. (c) The wall of the cat pictured in Figure 22.7b and c is greatly thickened, measuring 2.17 cm in this image.
The thickened wall has mottled echogenicity and protrudes into the gastric lumen. (d) The gastric wall of the cat in (c) exhibits a loss
of wall layering and appears anechoic in some areas. (e) On ultrasonography, the gastric wall of the cat in Figure 22.7d and e shows a
loss of wall layering, decreased echogenicity and thickening (1.16 cm in this image). (f) An additional image of the cat in (e) shows
enlargement, decreased echogenicity and irregular margination of lymph nodes (calipers) caudal to the stomach.
