Computed tomography in child abuse and cerebral contusion.

Cerebral contusion is considered to be the lesion leading to neurological sequelae of mental retardation and cerebral palsy in abused children. This has been difficult to document other than at autopsy or craniotomy by previously available techniques. Acute contusion or hemorrhage presumably secondary to contusion is readily documented by computed tomography (CT). We are reporting the cases of four children with alleged or suspected abuse and CT evidence of cerebral contusion. The contusion has been found both with and without external evidence of head injury.
