Median Arcuate Ligament Syndrome (MALS) is a medical condition that may result in significant abdominal pain. This pain is attributed to the compression of the celiac artery by the median arcuate ligament which can compromise blood flow and cause symptoms, such as abdominal pain shortly after eating meals, weight loss or an abdominal bruit, which may be heard by a doctor upon clinical examination.

Ultrasonography and Computed Tomography (CT) angiography along with 3-D imaging are used to screen for MALS. These screening tests allow doctors to determine whether or not patients suffer from the typical focal narrowing, often demonstrating a hooked appearance, in the proximal celiac axis, the primary characteristic of MALS.
