There is acute angulation with indentation upon the superior aspect of celiac axis. This scan was performed during inhalation, therefore this is a true stenosis secondary to median arcuate ligament.
Also, there is mild prominence and tortuosity of the splenic artery which may be compensating for long standing celiac axis stenosis.
In median arcuate ligament syndrome (MALS), compression of the celiac axis compromises blood flow and causes symptoms.
For all we know the patient has not presented to radiology with any complaint of abdominal pain. Therefore, strictly speaking this compression of the celiac axis would only be described, but it may not be necessarily MALS.
The imaging findings must therefore be correlated with the clinical history.
