Presentation
Abdominal distension. History of TB exposure.
Patient Data
Large ascites with mild nodular peritoneal thickening. Diffuse enhancing omental cake involving both the greater and lesser omentum. Nodular tumor throughout the leaves of the mesentery. Circumferential heterogeneously enhancing mass in the gastric antrum and pylorus.
Case Discussion
Extensive peritoneal carcinonomatosis due to gastric adenocarcinoma. Tumor infiltration helps to clearly identify the boundaries of the greater omentum which normally blends in with the intraperitoneal fat. The lesser omentum is comprised of the peritoneal covering of the stomach and proximal duodenum, and extends from the lesser gastric curvature toward the porta hepatis and is normally not seen. However in this case there is diffuse tumor infiltration which shows its boundaries.
