The Median Arcuate Ligament Syndrome (MALS) is a rare, controversial condition, caused by the compression of the celiac axis by the median arcuate ligament. The aim of this work is to show the contribution of CT Angiography with three-dimensional reconstructions in exploring this particular condition and its hemodynamic repercussion.

The Median Arcuate Ligament Syndrome is a controversial condition characterized by the compression of the celiac axis by a fibrous arch that passes over the proximal segment of the celiac artery. The celiac artery compression, better seen in expiratory phase, is detected mainly with some specific signs especially a focal narrowing of the proximal portion of the celiac artery, which gives a « hook-shaped » contour that helps differentiate it from other etiologies such as atherosclerosis. The Median Arcuate Ligament Syndrome was first described in...

Traditionally found on conventional angiography, the MALS is now very well studied on the high-resolution images of the aorta and its branches that can be provided by computed tomography (CT) angiography alond with a three-dimensional (3D) software. This non-invasive method is now known as a reliable technique for visualizing the anatomic anomaly. The celiac artery compression, better seen in expiratory phase, is detected mainly with the following signs : - A focal narrowing of the proximal portion of the celiac artery, usually 5mm from its...

The celiac compression by the median arcuate ligament is a well-known anatomic anomaly that can be recognized on a Computed Tomography Angiography by the narrowing of the proximal segment of the celiac artery with a « hool-shaped » appearance and post-stenotic dilation. These typical radiological findings, associated with clinical symptoms of intestinal angina and with no other known history or identified cause of the symptoms, must lead the radiographer and clinician to suspect the diagnosis of the Median Arcuate Ligament Syndrome.
