Dissecting mediastinal pseudocyst presenting with dysphagia: Role of multimodality imaging

Abstract

Pancreatic pseudocysts are the most common cystic lesions of the pancreas, accounting for 75-80% of such masses. Pancreatic pseudocyst with mediastinal extension is a rare clinical entity. Extrapancreatic fluid collections are more often detected in the lesser sac, in the anterior pararenal space, in the posterior pararenal space, in or around the left lobe of the liver, and in the spleen. The extra-abdominal extension is infrequent and the mediastinum is a rare site for the extension of the pancreatic secretion. We present a case of pancreatic mediastinal pseudocyst that presented with palpitations and dysphagia.
