Global Ischemia of The Cerebellum: The Dark Cerebellar Sign

Abstract

Comment We want to present the dark cerebellar sign, which is not known as well as the white cerebellar sign. White cerebellar sign refers to a normal cerebellum and brainstem that appear hyperdense in comparison to the supratentorial brain on non-enhanced CT. The cerebellum and brainstem are believed to be more resistant to hypoxia-ischemia than the supratentorial brain [1]. A diffuse hypodensity of the cerebrum is seen in cases of profound and sustained hypoxia. This may occur in prolonged cardiac arrest, poisoning IMAGES IN CLINICAL RADIOLOGY
