Parenchymal brain injuries in abusive head trauma

Area of Science:

• Pediatrics
• Neurology
• Forensic Medicine

Background:

• Abusive head trauma (AHT) results in severe morbidity and mortality in children.
• Survivors often face lifelong cognitive, motor, and behavioral impairments.
• Societal costs associated with caring for AHT victims are substantial.

Purpose of the Study:

• To review the parenchymal findings associated with abusive head trauma.
• To discuss current understanding of these brain injuries.
• To aid in the recognition of abusive head trauma.

Main Methods:

• Review of literature focusing on parenchymal injuries in AHT.
• Analysis of various types of brain damage, including hypoxic-ischaemic injury, clefts, contusions, and focal hemorrhages.
• Discussion of diagnostic challenges and recognition strategies.

Main Results:

• Parenchymal injuries in AHT encompass hypoxic-ischaemic damage, clefts, contusions, and focal hemorrhages.
• These findings, alongside skull fractures and extra-axial hemorrhages, are critical indicators.
• Distinguishing AHT-related injuries from other causes is essential.

Conclusions:

• Recognizing the spectrum of parenchymal findings is crucial for diagnosing abusive head trauma.
• A comprehensive understanding aids in identifying AHT and mitigating its devastating consequences.
• Early and accurate diagnosis is vital for child protection and support.
