Mesenteric injury with haematoma

Case contributed by Dr Dayu Gai


This 35 year old male was involved in a high speed motor vehicle accident. A CT trauma series was performed.

Patient Data

Age: 35
Gender: Male


  • Mesenteric injury with intraperitoneal haematoma, with associated hyperdense sentinel clot
  • Extensive homogeneous intraperitoneal free fluid
  • Splenic laceration
  • No intracranial, cervical spine or intrathoracic injury evident

Case Discussion

Mesenteric injury often results from compression and deceleration forces causing injury to the mesenteric plexus1. Note the hyperdense fluid surrounding the bowel, and tracking in between the mesenteric fat. The sentinel clot sign can be used to localise the source of occult haemorrhage in trauma.
