Abstract

Abusive head trauma is the leading cause of severe traumatic brain injury in children <2 years of age. Because the clinical presentation of children with abusive head trauma can be nonspecific, CT and MR imaging play an important role in distinguishing these cases from episodes of accidental head trauma. In this article, we review the pathophysiology, imaging appearance, and specificity of patterns of traumatic brain injury associated with abusive head trauma, and highlight recent updates in the understanding of these injuries.
