From: Fetal demise and Wernicke–Korsakoff syndrome in a patient with hyperemesis gravidarum: a case report
Magnetic resonance imaging (MRI) of the head using T2-weighted Fluid-Attenuated Inversion Recovery (T2/FLAIR) sequences obtained on hospital day 1 and repeated on transfer on HD13 demonstrates hyperintensities in the A fornix, bilateral medial thalami, B third ventricle, and C mammillary bodies and periaqueductal gray that leads to the floor of the fourth ventricle (not pictured). Aforementioned findings are demonstrated by the yellow arrows. The diagnosis of Wernicke Encephalopathy can be confirmed with these MRI scans demonstrating abnormalities; however, it is important to note that it is not sensitive as negative findings do not exclude the diagnosis of Wernicke–Korsakoff syndrome
