Abdominal vascular compression syndromes constitute a collection of infrequent but clinically important conditions caused by external compression of abdominal vessels or by vascular structures exerting pressure on hollow organs. Key syndromes include Median Arcuate Ligament Syndrome (MALS), Nutcracker Syndrome (NCS), Superior Mesenteric Artery (SMA) syndrome, SMA-like syndrome, Retrocaval Ureter & Portal Biliopathy. These conditions are often underrecognized, as they can present with vague abdominal or urinary symptoms, while many affected individuals remain symptom-free. This review focuses on essential CT imaging findings and clinical correlations that assist in diagnosing symptomatic patients.
