Weight Loss-associated Superior Mesenteric Artery Syndrome, an Unusual Condition in a Peruvian Patient: A Case Report.

Computed tomography angiography demonstrated narrowing of the aortomesenteric angle. The patient underwent conservative medical management, focusing on relieving obstruction and nutritional support.
