Non‐missile head injury: report of a patient surviving for 6 years

Abstract

A female patient with non-missile head injury is described. She showed slight improvement in her level of consciousness, and survived for 6 1/2 years after injury. At autopsy, the white matter lesions were localized rather than diffuse in distribution. In addition to lesions in the corpus callosum, anterior commissure and dorsolateral quadrant of the rostral brain stem, those in the parasagittal cerebral white matter, and in the hilus of the dentate nucleus and superior cerebellar peduncle were considered to be due to primary axonal injury. A cavity in the frontal white matter was remarkable in that there was no evidence to indicate expansion of the lesion due to haemorrhage. These features suggested that the injurious physical forces had acted parallel to the direction of the axons.
