Achalasia-associated superior mesenteric artery syndrome with massive gastric dilatation

The patient has a very rare combination of achalasia and superior mesenteric artery syndrome, presenting with massive dilatation of the stomach with no perforation.Early detection through computed tomography angiography and early decompression are essential to prevent potentially fatal complications, including gastric rupture.This case adds to the limited literature describing achalasia-superior mesenteric artery overlap and reinforces the need for a high degree of clinical suspicion when symptoms diverge from baseline.
