Presentation
Weight loss, abdominal pain and non-bilious vomiting for the recent two months. Elevated ESR and CRP in the blood test.
Patient Data



Asymmetrical increased wall thickness due to tumoral infiltration is present in the distal gastric antrum, and pylorus causes gastric overdistention. Mild surrounding fat stranding and several regional prominent lymph nodes are also seen.
Two stones less than 24 mm are seen in the gallbladder.
Several non-enhanced simple cortical cysts are seen in both kidneys. A 5mm stone is noted in the lower calyx of the right kidney. Two 6mm and 4mm stones are also observed in the lower calyces of the left kidney.
A 70 mm thin-walled unilocular cyst without enhancing solid components is noted in the lower para-aortocaval regions, most consistent with lymphangioma.
A small fat-containing umbilical hernia is seen.
In imaged portions of the lower thorax, cardiomegaly and mild pericardial effusion are seen.
The prostate gland is enlarged.
Case Discussion
Pathology-proven distal gastric adenocarcinoma that causes pyloric stenosis and gastric outlet obstruction.
Gastric outlet obstruction can be due to malignant or benign causes. Duodenal or gastric peptic ulcers are the most common, and distal gastric adenocarcinoma is the second most common cause.
