Pancreatic trauma with posttraumatic pseudocyst and ductal injury

Case contributed by Sriman Reddy M
Diagnosis certain

Presentation

The patient reports being struck by an elephant and has been experiencing upper abdominal pain since the incident.

Patient Data

Age: 20 years
Gender: Male

Ill-defined area of non-enhancement noted in the head and body of the pancreas, which is seen to communicate with the MPD with surrounding mild fat stranding and collection - likely AAST grade-III pancreatic parenchymal injury with ductal injury.

The collection is noted in the right perirenal space with thickening of perirenal fascia - likely hemorrhagic collection.

Visualized thorax shows bilateral mild pleural effusion with atelectasis of adjacent lung parenchyma.

A well-defined collection of size 3.3 x 3.1 cm is noted in the pancreatic head and extends into the pancreaticoduodenal groove. The main pancreatic duct is seen to communicate with the collection - suggestive of post-traumatic pancreatic pseudocyst

The common bile duct is normal in size. The distal CBD is mildly compressed by the collection leading to mild prominence of CBD ( 9.4 mm ). No calculus was seen.

No filling defects were identified within the intrahepatic or extrahepatic biliary tree.

Case Discussion

CT findings are in favor of AAST grade-III pancreatic parenchymal injury with ductal injury (pancreatic trauma).

MR findings show post traumatic pancreatic pseudocyst with dilated CBD caused by compression of CBD by collection.
