Characteristics of esophageal diverticula using computed tomography and three-dimensional reconstruction in a Maltese dog.

A 7-year-old intact female Maltese dog was referred with ptyalism and intermittent vomiting but no regurgitation for over I month. Survey radiographs including a contrast study revealed a large circular dilated cavity from the carina to the diaphragm. Additionally, multi-detector computed tomography and three-dimensional reconstruction were performed. These images revealed large idiopathic distal esophageal diverticula. This case report represents the first report using multi-detector computed tomography and three-dimensional reconstruction for evaluation of esophageal diverticula in a dog.
