Vascular ring anomalies are congenital malformations of aortic arches arteries that usually cause megaesophagus in affected animals but this phenomenon is extremely rare in cats. This clinical report demonstrates an unusual form of vascular anomaly in a domestic short hair kitten. The animal was referred with history of moist cough, dyspnea, fever, and persistent regurgitation. Barium esophagram, demonstrate esophageal body dilation cranial to the base of the heart. Primary conservative treatment was done but the owner refused the surgical correction. The animal was euthanized due to her poor condition and the definitive diagnosis of vascular ring anomaly was made in postmortem examination. According to our knowledge, this is the first report of megaesophagus caused by an aberrant right subclavian artery concomitant with the brachiocephalic trunk in a cat.
