Presentation
Out of hospital cardiac and respiratory arrest.
Patient Data
Grey-white matter differentiation of the cerebrum and cerebellum is preserved, however there is subtly reduced density of the cerebrum relative to the cerebellum, suggesting mild/early diffuse edema. No sulcal effacement, and ventricles are normal in appearance.
No intracranial hemorrhage or contusion. No subfalcine, transtentorial or tonsillar herniation.
Global loss of grey-white matter differentiation and relative increased hypoattenuation of the deep grey matter nuclei is demonstrated. The ventricles sulci more slitlike in appearance with increased effacement of the basal cisterns consistent with progression of cerebral edema. No intracranial hemorrhage. No uncal or tonsillar herniation.
Appearance are consistent with global hypoxic injury.
