RESUMEN
Median arcuate ligament syndrome (MALS) is a rare gastroenterological illness that arises from the compression of the celiac trunk by the fibrous arch known as the median arcuate ligament, which connects the muscular tendon of the diaphragm to the vertebral column. It is hypothesized that this syndrome arises due to the inadequate caudal migration of the celiac trunk during embryogenesis, although the exact pathophysiology behind this disease process remains unclear. While MALS is classically associated with a triad of post-prandial pain, weight loss, and epigastric bruit, the triad is often incomplete due to variations in vascular structures with collateral circulation from adjacent vessels. When symptoms are present, they can be vague and often characterized as unexplained nausea, vomiting, diarrhea, or flatulence. Frequently, MALS is identified incidentally upon imaging of the abdomen in response to these nonspecific complaints. We present the case of a patient suffering from MALS in which a rare anatomic variant of the celiac trunk was identified.
