Delayed and progressive brain injury in children and adolescents with head trauma

We performed serial CT scans on 351 children and adolescents with serious closed-head injury. Delayed or progressive lesions were encountered in 145 (41%). The occurrence of such delayed cerebral injuries correlated with the severity of the initial head trauma, with the presence of major extracranial injury and with studies of coagulopathy on admission. The presence of delayed cerebral injury had a profound influence on survival and recovery from head trauma, especially when the initial severity of the head injury was taken into account. We conclude that serial CT scans provide a reliable means of diagnosing and following the progress of delayed cerebral injury in the pediatric population.
