Case contributed by Ali Alsmair
Diagnosis probable


A young female patient presented with long-standing post-prandial upper abdominal pain.

Patient Data

Age: 25 years
Gender: Female

Distention of the stomach and duodenum proximal to the SMA level where it appears to be compressed between the aorta and SMA, with aortomesenteric angle measures about 18° and aortomesenteric distance measures about 5 mm, features are highly suggestive of Superior mesenteric artery syndrome.
Incidental findings of Retroaortic left renal vein, hepatic steatosis and incomplete Annular pancreas are noted.

Case Discussion

The diagnosis of SMA syndrome is based on clinical symptoms and radiologic evidence of obstruction.

The radiological findings alone are not enough for the diagnosis.
