Radiographically obscure cervicocranial injuries can be missed. Abnormal prevertebral soft-tissue contours on imaging warrant computed tomography (CT) for definitive diagnosis of acute cervical spine injuries.

Area of Science:

  • Radiology
  • Orthopedic Surgery
  • Emergency Medicine

Background:

  • Acute injuries to the cervicocranium (occiput to C2) can be difficult to detect radiographically.
  • Subtle fractures or ligamentous injuries may cause minimal displacement or altered anatomy.
  • Normal prevertebral soft-tissue contour is key for initial assessment.

Purpose of the Study:

  • To evaluate the utility of computed tomography (CT) in diagnosing cervicocranial injuries.
  • To determine the diagnostic yield of CT when prompted by abnormal prevertebral soft-tissue contours.

Main Methods:

  • Review of imaging studies for cervicocranial injuries.
  • Assessment of prevertebral soft-tissue contour in relation to the anterior cortical margin.
  • Correlation of abnormal soft-tissue findings with CT results.

Main Results:

  • Abnormal cervicocranial prevertebral soft-tissue contours indicate potential hemorrhage.
  • CT scans prompted by these soft-tissue abnormalities revealed a 16% positive injury rate.
  • This rate is approximately three times higher than previously reported for acute cervical spine injuries.

Conclusions:

  • Abnormal prevertebral soft-tissue contour is a significant indicator of underlying cervicocranial injury.
  • Computed tomography (CT) is crucial for detecting subtle or radiographically obscured cervicocranial injuries.
  • Utilizing CT based on soft-tissue findings improves the detection rate of acute cervical spine trauma.
