Radiographs: The caudal intrathoracic esophagus is distended and filled with soft tissue opacity. In addition, there is a fat dense mass of tissue best noted on the DV projection just lateral to the cardiac silhouette. The rest of the pulmonary parenchyma is within normal limits. The cardiovascular structures are also within normal limits. There is granular mineral debris within the gastric lumen, and the liver has rounded borders.
Ultrasound: There is a complex mass associated with the cardia of the stomach and esophagus. Focal regions of mineralization and marked loss of wall layering is present circumferentially in this region. This mass crosses the diaphragm into the thorax and involves a portion of the stomach.
