Background
Injuries to the pancreas in blunt trauma are uncommon but carry a high morbidity and mortality risk. Pancreas is an organ located in the center of the abdomen but may be overshadowed by the common injuries of the surrounding organs, hence "hidden in plain sight". 

Educational Goals
The purpose of this educational exhibit is: (1) To illustrate critical imaging findings and grading system in blunt traumatic pancreatic injuries at Computed Tomography (CT). (2) To discuss the management for pancreatic injuries with an emphasis on pitfalls and limitations of pancreatic injuries. (3) To discuss the role of advanced imaging in acute and follow-up evaluation of pancreatic injuries. The exhibit will maximize the use of real-life cases and images.

Key Imaging Findings
There are direct and indirect signs of pancreatic injuries. Direct signs include lacerations, contusions and hematomas. Indirect signs include peripancreatic fluid, hemorrhage or stranding. A key distinguishing factor for management of pancreatic injuries is to determine if the pancreatic duct is involved. Direct visualization of the ductal involvement or greater than 50% involvement of the pancreatic thickness are signs of ductal involvement. The American Association for Surgery of Trauma grading scheme for pancreatic trauma is presented and is a standardized tool for communication of the injuries with the surgical colleagues. The role of Magnetic Resonance Imaging (MRI) in acute setting is not established. Magnetic Resonance Cholangiopancreatography (MRCP) with secretin administration has been shown to be equivalent or superior to Endoscopic Retrograde Cholangiopancreatography (ERCP) in the assessment of ductal injuries. The radiologist should also be aware of common limitations and pitfalls of pancreatic trauma including contribution from injuries to the surrounding organs, mimics such as pancreatic clefts and non-traumatic causes of parenchymal abnormalities such as pancreatic neoplasms or pancreatitis. Recognizing the evolution of complications such as abscess or pseudocyst formation is important in the follow-up imaging of pancreatic trauma. 

Conclusion
This exhibit will offer an opportunity to review the imaging appearance of blunt traumatic pancreatic injuries and emphasize the role of radiologist in detection and management of these life-threatening entities.
