Neuroimaging: what neuroradiological features distinguish abusive from non-abusive head trauma? A systematic review

Abstract

Objectives To identify the evidence base behind the neuroradiological features that differentiate abusive head trauma (AHT) from non-abusive head trauma (nAHT). Design Systematic review. Setting Literature search of 14 databases, websites, textbooks, conference abstracts and references (1970–February 2010). Studies had two independent reviews (three if disputed) and critical appraisal. Patients Primary comparative studies of children Main outcome measures Neuroradiological features that differentiated AHT from nAHT. Results 21 studies of children predominantly Conclusion Multiple SDH over the convexity, interhemispheric haemorrhages, posterior fossa SDH, HII and cerebral oedema are significantly associated with AHT and should be considered together with clinical features when identifying the condition.
