Projectile expectoration associated with an esophageal diverticulum in a cow.
An adult Milking Shorthorn cow developed a pulsion diverticulum of the esophagus, close to the esophageal hiatus. Clinical signs were loss of condition and projectile expectoration of chewed ingesta, as far as 2 m, accomplished by forceful expiration clearing the regurgitated ingesta from the pharynx. The lesion was detected by digital palpation through the cardia, via a rumenotomy incision.
