What is the cause for the patient's presentation?
Not the AAA. There is pooling of contrast in the gastric antrum, in keeping with active bleeding.
No evidence of AAA rupture. No retroperitoneal haemorrhage or new stranding.
On portal venous phase there is accumulation of contrast pooling in the antrum of the stomach. No free gas to suggest perforation. No small bowel or colonic active bleeding. Small bowel demonstrates normal enhancement.
