Patient Data
Age: 14
Gender: Female
From the case:
Superior mesenteric artery syndrome

Significant gastric dilatation is noted proximal to the level of 3rd part of duodenum that is compressed by the close proximity of superior mesenteric artery to the aorta. Diminished fat plane is noted between the superior mesenteric artery and aorta.

Axial
- aortomesenteric distance = 7.6 mm (lower limit of normal = 10 mm)
- aortomesenteric angle = 16.8o (lower limit of normal = 25o)
Case Discussion
Close proximity and acute angulation between the superior mesenteric artery and aorta is caused by scanty interposing fat, resulting in compression of the 3rd part of duodenum with proximal gastric dilatation, explaining the patient's complaint. Such findings are suggestive of superior mesenteric artery syndrome.
