CT findings in a dog with chronic giant hypertrophic gastritis: Ménétrier‐like disease

A 9‐year‐old male's entire Boston Terrier was presented with persistent hyporexia and weight loss for 6 weeks prior to referral admission. A CT scan showed marked hypertrophy of the rugal folds protruding into the gastric lumen, which had a cerebriform appearance. Changes were consistent with the ultrasonographic findings, which showed marked hyperechogenicity of the gastric mucosa, mucosal cysts, and otherwise normal wall layering. Histopathology of the fundic gastric mucosa showed foveolar hyperplasia and cystic dilation which were findings consistent with Ménétrier‐like disease. Based on the reviewed literature, this is the first case report describing CT findings of Ménétrier‐like disease in a dog.
