Plain-English summary
A 5-year-old Siamese cat was brought to the vet for sudden vomiting and regurgitation. Imaging tests showed that a twisted aorta was pressing on the esophagus, which can lead to swallowing difficulties, a condition similar to one seen in humans. The vet also found that a hairball had caused a blockage in the esophagus. After treating the cat conservatively, the symptoms improved, and the cat started feeling better.

Abstract
A 5-year-old Siamese cat presented with acute regurgitation and vomiting. Multimodal imaging revealed a tortuous thoracic aorta causing extraluminal esophageal compression. This vascular anomaly shares features with a rare human syndrome known as dysphagia aortica. The absence of hypertensive cardiomyopathy suggested a congenital malformation, despite the delayed presentation. Endoscopy confirmed esophageal stenosis with ulcerative lesions secondary to a trichobezoar obstruction at the stenotic site. Conservative management led to clinical improvement. This report documents, to our knowledge, the first feline case of presumed dysphagia aortica of likely congenital origin, expanding the spectrum of vascular causes for esophageal obstruction.
