Transient White Matter Diffusion Restriction in a Pediatric Patient With Diffuse Axonal Injury.

Traumatic brain injury (TBI) is a serious public health problem due to its high incidence worldwide and possible sequelae, especially in the pediatric population. Imaging studies play a leading role in evaluating pathologies requiring early surgical management and the prognosis of long-term sequelae. Diffuse axonal injury (DAI) is one of the most severe complications of TBI, and few reports in the literature are associated with cytotoxic edema. We present a case of a pediatric patient with DAI with extensive areas of transient diffusion restriction in the white matter, which we consider to be related to cytotoxic edema.
