An 89-year-old man came to the emergency department due to vomiting, pain, and bloating of 12h progression. Physical examination revealed a pulsatile abdominal mass. A computed tomography scan showed gastric retention (fig. 1, blue arrow) secondary to duodenal compression from a large abdominal aortic aneurysm (figs. 1 and 2, green arrow). A filiform duodenum (fig. 2, red arrow) was observed with proximal segment dilation and normalization of the caliber distal to the aneurysm. Duodenal compression from an abdominal aortic aneurysm is known as aortoduodenal syndrome. It is a very rare entity that usually presents with vomiting, weight loss and pain, and abdominal distension. It should be suspected in the presence of obstructive symptomatology and a pulsatile abdominal mass. Diagnosis and the ruling out of other causes are confirmed through contrast-enhanced abdominal CT scan. Treatment is based on initial stabilizing of the patient with fluid and electrolyte support and gastric decompression, so that later elective surgery can be performed.
