  • Occasionally widening of the paravertebral line indicates a haematoma due to a spinal fracture

T-spine - Paravertebral haematoma - AP

  • In this case there is marked widening of the mediastinum due to haematoma formation
  • There is loss of clarity of the cortical outline of the vertebral bodies indicating fractures - much more easily seen on the CT study (see below)
