From Chapter 15 – Abdominal Cavity, Lymph Nodes, and Great Vessels
Figure 15.17. Carcinomatosis and sarcomatosis. A and B: In these two cats with pancreatic adenocarcinoma, nodules of variable echogenicity are disseminated in the omentum and mesentery. C: In one of these cats (same as in A), hypoechoic nodules also invade the peritoneal lining and adjacent abdominal wall. D: In this dog with undifferentiated soft tissue sarcoma, masses were found throughout the abdominal cavity, consistent with sarcomatosis.
