Etiology/Pathophysiology:
Mechanisms are translational (direct impact) and rotational
(acceleration/deceleration). Shaking the child produces rotational
forces that cause shearing injuries. Head injury is the primary cause
of morbidity and mortality in abused children, with it being more
common in children less than 2 years of age.
Pathology:
Not applicable
Imaging Findings:
The most common lesion seen in the head is a subdural hematoma which
is seen most commonly along the convexities and along the posterior
interhemispheric fissure. The subdural hemorrhages may be of varying
ages. Subarachnoid hemorrhage may be seen acutely along with cerebral
edema, and cerebral contusion. Long term encephalomalacia,
ventriculomegaly and porencephaly may be seen.
