Abstract
The mediastinum is a relatively uncommon site for a pancreatic pseudocyst. Two such patients were presented, along with a review of 14 additional cases from the English literature. In most cases the pseudocyst was located in the posterior mediastinum, with entry to the mediastinum via the aortic or esophageal hiatus. The most common presenting symptoms were chest or abdominal pain and dyspnea. Displacement of the esophagus and stomach anteriorly and to the left on the upper gastrointestinal series and an associated mediastinal mass were the most helpful radiographic manifestations.
