Mediastinal Extension of a Pancreatic Pseudocyst: A Rare Intrathoracic Complication of Pancreatitis

Figure 1

CT pulmonary angiogram. (a) Axial image at the level of the left atrium reveals a large fluid collection in the posterior mediastinum, anterior to the esophagus and aorta, with a thickened and enhancing wall. (b) Axial image at the level of the pancreatic body reveals a similar fluid collection at the level of the pancreatic body. Also noted is heavy calcification of the pancreatic parenchyma, in keeping with chronic pancreatitis. (c) Sagittal CT demonstrates the continuous fluid collection extending from the posterior mediastinum at the level of the carina, to the level of the pancreas.
