Gastroesophageal intussusception and extreme esophageal dilatation secondary to bilateral laryngeal paralysis in a cat.

Gastroesophageal intussusception, extreme esophageal dilatation, and laryngeal paralysis are individually rare clinical entities in cats and the simultaneous occurrence in a single animal has not been described. We describe these 3 conditions occurring concurrently in a geriatric cat, and resolution of the cat's clinical signs after treatment with unilateral arytenoid lateralization. This finding supports the need for thorough history taking and examination in cats with extreme esophageal dilatation to determine if upper respiratory tract abnormalities are present, as appropriate treatment might resolve the esophageal dilatation.
