Differential diagnoses to consider are;
- diffuse glioma, however, there is no asymmetry in the T2 hyperintensity,
- lymphoma - no enhancement noted
- top of the basilar syndrome - no PCA or SCA involvement
- hypoxic-ischemic-encephalopathy - basal ganglia are unaffected
- deep cerebral venous thrombosis - often accompanied by hemorrhage, which is absent here
- Wernicke's encephalopathy - mammillary, hypothalamic and PAG involvement is not seen
