Pancreatic trauma - ultrasound

Case contributed by Maulik S Patel
Diagnosis almost certain

Presentation

Blunt abdominal trauma due to a fall from a height about two weeks ago. Severe abdominal pain, vomiting, and abdominal distension for the last few days.

Patient Data

Age: 30 years
Gender: Male
ultrasound

Free fluid in the perihepatic, hepatorenal, splenorenal, paracolic regions, and pelvis. An anechoic full-thickness fluid cleft in the pancreatic body sparing some parenchymal tissue on the cranial side. The defect is left to the superior mesenteric vein-portal vein axis. The rest of the pancreas shows a normal echopattern. Normal liver, spleen, and kidneys.

x-ray

No free gas under the domes of the diaphragms. Increased ground glass density. Few small bowel air-fluid levels.

Case Discussion

The case shows a full-thickness injury involving the distal pancreas. The pancreatic duct is injured which may be the cause of large-volume ascites. Paracentesis is required to check the levels of amylase and protein to rule in/rule out the pancreatic origin of the ascites due to a ruptured pancreatic duct. A CT scan is needed as an isolated pancreatic injury is uncommon.
