Pseudo-subarachnoid hemorrhage

Discussion:

Non-contrast CT Brain shows generalized sulcal effacement and cerebral hypoattenuation with loss of grey-white differentiation consistent with cerebral edema secondary to intracranial hypoxia. The basal cisterns appear dense  likely due to combination of cistern effacement, possible thrombus within intracranial vessels and surrounding relatively low attenuating brain. This appearance has been termed pseudo-subarachnoid hemorrhage. Brain death was subsequently confirmed with nuclear medicine cerebral perfusion scan.
