Imaging findings in abusive head trauma (AHT).

Brain imaging plays a key role in accurately identifying abusive head trauma (AHT). An exact and rapid diagnosis is needed due to the extreme severity of AHT, since there is a risk of neurological sequelae and potentially fatal recurrence. Several medical specialists will work collaboratively to detect and confirm abuse in children: the radiologist has a leading role in this approach. This article describes the most common neuro-imaging patterns of AHT, including extra axial, intra axial, bony, and ligamentous lesions, with a special focus on the dating issue and the differential diagnosis.
