OBJECT: The purpose of this study was to describe late neuropathological MRI findings in pediatric severe head injury and to explore the relationship between these lesions and cognitive sequelae.
METHODS: Thirteen infants with severe head trauma (Glasgow 6) were included in this investigation. Clinical examination, a battery of tests designed to assess neurophysiological status, and MRI investigations of the brain were obtained in periods ranging between 8 and 20 months after the accident. Hemosiderin deposits, encephalomalacia, and cerebellar atrophy were the most frequent traumatic sequelae. The lesions were located in frontal lobes, the basal ganglia, and the cerebellum. Six patients had cerebellar atrophy associated with frontal or temporal postraumatic lesions. Cerebellar clinical dysfunction was observed in only 3 of these patients. Performance on tests evaluating frontal lobe functions was depressed in 5 of them.
CONCLUSIONS: Late MRI after severe head trauma in our pediatric population showed unexpected cerebellar atrophy. Its correlation with prefrontal dysfunction is difficult to confirm because of its association with other parenchymal post-traumatic lesions. Further research involving a larger sample of patients with brain injury of varying severity is in progress, to investigate whether cerebellar atrophy could be a consequence of severe head trauma.
