Insights

Neuroimaging findings like hypoxic-ischemic injury and spinal ligamentous injury are associated with poor outcomes in abusive head trauma cases. These findings can help predict prognosis in affected children.

Area of Science:

  • Pediatric Radiology
  • Child Abuse Forensics
  • Neurology

Background:

  • Abusive head trauma (AHT) is a leading cause of severe injury and death in young children.
  • Radiological imaging is crucial for diagnosing AHT, but no single finding is definitively diagnostic.
  • Identifying prognostic indicators from neuroimaging is essential for patient management.

Purpose of the Study:

  • To determine the prevalence of brain and spine neuroimaging findings in children with AHT.
  • To analyze the association between specific neuroimaging findings and clinical factors.
  • To identify neuroimaging findings that may serve as prognostic indicators for AHT outcomes.

Main Methods:

  • Retrospective study of 102 children diagnosed with AHT between January 2018 and February 2021.
  • Analysis of patient demographics, survival, Glasgow Coma Scale (GCS) scores, and hospital/ICU lengths of stay.
  • Categorization of brain findings (classic/nonclassic) and assessment of spine MRIs for ligamentous injury, fractures, and hemorrhage.

Main Results:

  • Subdural hematoma was the most common classic finding (83.3%); bridging vein thrombosis was the most common nonclassic finding (30.4%).
  • Spinal ligamentous injury was present in 23/49 patients.
  • Hypoxic-ischemic injury correlated with mortality (P=.0001) and lower GCS scores (P<.0001). Intraventricular hemorrhage, diffuse axonal injury, hypoxic-ischemic injury, arterial stroke, and spinal ligamentous injury were associated with longer hospital and/or ICU stays.

Conclusions:

  • Specific neuroimaging findings, including hypoxic-ischemic injury and spinal ligamentous injury, are significantly associated with adverse outcomes in AHT.
  • The presence of intraventricular hemorrhage, diffuse axonal injury, hypoxic-ischemic injury, arterial stroke, and/or spinal ligamentous injury may indicate a poor prognosis in pediatric AHT.
  • These findings aid in the prognostic assessment of children with abusive head trauma.
