Esophageal hiatal hernia and megaesophagus complicating tetanus in two dogs.
Two dogs with tetanus developed transient megaesophagus and hiatal hernia associated with gastroesophageal reflux and regurgitation. The megaesophagus and hiatal hernia were diagnosed radiographically and resolved with resolution of the tetanus. These 2 cases, plus previously reported cases, indicate that tetanus can cause megaesophagus and esophageal dysfunction. Therefore, thoracic radiography should be included as part of the diagnostic evaluation of dogs suspected of having tetanus.
