Corresponding post-contrast T1WI (B) reveals periventricular enhancement (arrows). Hyperintensity in the thalami (arrows), mesencephalon, superior cerebellar peduncles (arrowheads) and along the fourth ventricle on another FLAIR image (C). Post-contrast T1WI (D) shows symmetric enhancement in most of the affected regions (arrows). Figure 3. Axial FLAIR images show abnormal increased signal along the medial nuclei of the thalami (arrows in A) as well as in the periaqueductal region (arrow in B) and along the third ventricle (arrowheads in B).
Enhancement of the mammillary bodies is most frequently observed in the alcholic population and may be the only imaging finding. Degree of enhancement is quite variable. Hemorrhagic transformation is rare. Brain atrophy develops in chronic WE, in particular of the fornices and mammillary bodies, while T2 hyperintensity becomes less obvious. • increased T2 signal in the pulvinar thalami • involvement of putamen and caudate, cortical gray matter • extensive areas of reduced diffusion involving cortical and deep gray matter Pertinent Clinical Information WE is an acute neurologic disorder resulting from thiamine (vitamin B1) deficiency and its incidence is underestimated in both adult and pediatric patients.
Diffusion changes persist for weeks to months, and may disappear in the late stages of disease. A prominent symmetrical hyperintense T2 and DWI signal in the pulvinar thalami (the “pulvinar sign”) is characteristic of variant CJD (vCJD). Involvement of the medial thalamus is also common, and the combination of both findings has been referred to as the “hockey-stick” sign. Signal changes in the pulvinar with sporadic CJD (sCJD) are less pronounced than changes in the striata. • • • • Pertinent Clinical Information The most common form of CJD, accounting for 85–90% of cases of human prion disease, is the sCJD.
