MRI Findings In Acute Wernicke's Encephalopathy, Caused By Hyperemesis Gravidarum

A 25-year old pregnant female with history of confusion and drowsiness for 02 days was referred by neurophysician for MRI brain. MRI demonstrated T2W/FLAIR hyper intensities in medial thalami, periaqueductal areas with variable diffusion restriction, apparent as hyper intense signal on DWI and no signal change on ADC mapping that was typically consistent with Wernicke's encephalopathy. A high index of suspicion is necessary, as delayed or lack of treatment can lead to high morbidity and mortality.
