Brain trauma and diffuse axon injury in the Corpus Callosum

Diffuse axonal injury:

Trauma that is strong enough to break long slender blood vessels is usually strong enough to break long delicate axons, too.  Therefore, the presence of gross microhemorrhages in long white matter tracts, such as the corpus callosum, strongly suggests that diffuse axonal injury will be seen on microscopic evaluation of the axons comprising these white matter tracts.
