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

Figure 2

MRI/MRCP examination of the abdomen with and without contrast. (a, b) MRCP sequences demonstrate a hyperintense tubular fluid collection extending towards the mediastinum and a tortuous dilated pancreatic duct with multiple ectatic side branches. (c) Axial T2 HASTE sequence demonstrates a hyperintense fluid collection in the posterior mediastinum, anterior to the esophagus and aorta. (d, e) Axial and coronal postcontrast T1 sequences reveal a hypointense fluid collection and enhancement of the surrounding wall of the collection. In addition, the coronal image demonstrates communication of the collection between the peripancreatic region and the mediastinum.
