Abstract

Objective: To compare occult brain injuries on neuroimaging in clinically asymptomatic children under 20 months due to abusive versus accidental head trauma.


Subjects and Methods: A retrospective review of 58 children under 20 months who underwent neuroimaging for possible abusive trauma was performed. The data collected were demographics, neurological signs/symptoms, imaging findings, and disposition (abusive or accidental).


Results: The disposition of 31 subjects was abusive trauma and 27 were accidental. At presentation, 8/31(25.8%) children with abusive injury and 15/27(55.6%) with accidental injury were neurologically asymptomatic. Neuroimaging was abnormal in 6 of 8 (75.0%) asymptomatic children with abusive injury, and 13/15 (86.7%) children with accidental trauma. No significant (P = 0.59) difference in frequency of abnormal neuroimaging was seen between the asymptomatic abusive and accidental trauma groups.


Conclusions: Although victims of abusive trauma under 20 months of age are less often neurologically asymptomatic compared to accidental trauma victims, neuroimaging revealed a high rate of occult traumatic brain injury in both groups.


Key Points


* Infants and young children who are victims of accidental trauma are often screened more aggressively for occult head injuries than those who are victims of abusive trauma.


* This study shows that children <20 months of age who are victims of accidental, as well as abusive trauma have a similar rate of asymptomatic head injuries detected with neuroimaging.


* Because neuroimaging findings of head trauma may be used for evidentiary reasons, we suggest that screening neuroimaging be carefully considered during the evaluation of infants and young children who may have suffered abusive head injuries regardless of presence or absence of symptoms.
