Abstract

A 6-year-old female Pekingese dog, weighing 3.85 kg was presented with regurgitation, ptyalism, weight loss and anorexia. The dog was cachexic and severely dehydrated. Physical examination of the dog confirmed upper respiratory noise, which was classified as a stridor most apparent on inspiration, respiratory effort with stenotic nares. Upper respiratory signs were thought to be caused by brachycephalic syndrome. On the lateral thoracic radiograph, the caudal one third of the esophagus was visible as a soft tissue band. CT revealed oval-shaped, soft tissue attenuating mass in size of $2.3{\times}1.0{\times}1.1cm$ arising from caudal one third of the esophagus. The mass was protruding from esophageal wall to lumen and irregular margined with heterogenous contrast enhancement. The wall of cardia and fundus was focally thickened. Gastric lymph node was enlarged with contrast enhancing. On histopathologic examination, esophageal mass was confirmed as papillary adenocarcinoma, and the gastric sample showed the same result. In human, adenocarcinoma commonly occur in esophagus and cardia, but it has not been commonly reported in veterinary medicine. This report described computed tomographic features of adenocarcinoma of the esophagocardia region in a Pekingese dog with brachycephalic syndrome.
