Case Discussion

In median arcuate ligament syndrome; the celiac trunk demonstrates a focal stenosis with a characteristic hooked appearance due to the indentation on its superior surface. This appearance may be seen in normal people if imaging is acquired in expiration. So, the clinical history is mandatory to suggest such diagnosis. It usually presents in young age between 20 and 40 years. The young age of the patient and the characteristic hooked appearance distinguish this syndrome from the main differential diagnosis of atherosclerotic disease.
