Info

Gastric overdistention is present due to asymmetrical tumoral infiltration of the antrum and pylorus. Surrounding fat stranding and a few enlarged regional lymph nodes are also observed. There is no sign of local tumoral invasion.

A few peritoneal soft tissue density masses are scattered, inferring tumoral deposits.

A few subcentimeter simple cortical cysts are seen in the kidneys.

The prostate gland is enlarged.

Case Discussion

Gastric outlet obstruction (GOO) due to antral and pylorus tumoral infiltration, pathology-proven adenocarcinoma, with enlarged regional lymph node and peritoneal seeding.
