[Child abuse. Important findings in diagnostic imaging].

The radiologist must be familiar with all signs of the battered child syndrome to prevent misinterpretation. Important clinical signs are hematoma at different ages and in uncommon locations. The principle imaging signs are subdural hematoma, brain contusion and multiple skeletal injuries sometimes at different ages. The parents or the persons responsible for care often neglect mentioning an injury. The principle signs are shown and a diagnostic flow chart is presented.
