Conclusion

Acute pancreatic ruptures are difficult to diagnose with ultrasound. When there is no blood in the defect, they can easily be overlooked. Ultrasound is very sensitive in detecting fluid, but parenchymal lesions can sometimes be missed. CT is more sensitive than ultrasound in detecting parenchymal lesions. The patient was discussed with a  larger pediatric trauma centre, but because he remained hemodynamically stable the treatment of choice remained conservative treatment. The fluid collections that developed were percutaneously drained under ultrasound guidance.
