Initial CT Brain demonstrates diffuse cerebral white matter hypoattnuation including involvement of the corpus callosum. There is associated generalised cerebral sulcal effacement. Brain biopsy was performed the following day showing acute haemorrhagic leukoencephalitis (see path report below)
CT Brain 4 days later shows interval progression of the white matter hypoattenuation and the development of basal cistern effacement (descending transtentorial herniation) from raised intracranial pressure.
