A pediatric case of blunt carotid injury presented with a hyperdense middle cerebral artery (MCA) sign on CT, indicating early cerebral ischemia. This sign aided in detecting stroke before focal neurological deficits appeared.

Area of Science:

  • Pediatric Neurology
  • Neuroradiology
  • Trauma Surgery

Background:

  • Blunt carotid artery injuries in children are rare but can lead to severe neurological deficits.
  • Early detection of cerebral ischemia is crucial for timely intervention and improved outcomes.

Observation:

  • A 5-year-old boy sustained blunt carotid injury after being struck by a vehicle.
  • Initial CT revealed a skull fracture, but no intracranial lesions.
  • A repeat CT demonstrated a hyperdense middle cerebral artery (MCA) sign, preceding focal neurological deficits.

Findings:

  • The patient developed left hemiparesis 18 hours post-injury, with CT confirming right MCA territory infarction.
  • Angiography revealed a right internal carotid artery occlusion with inadequate collateral circulation.

  • The hyperdense MCA sign was a key indicator of early cerebral ischemia.

    • Implications:

    • The hyperdense MCA sign is a valuable early marker for detecting cerebral ischemia in pediatric blunt carotid artery injuries.
    • Prompt recognition can guide management strategies, even in the absence of overt neurological signs.
    • This case highlights the importance of advanced imaging in pediatric trauma to identify subtle but critical vascular injuries.
