Abstract
BACKGROUND: Wernicke's encephalopathy is a potentially reversible disorder. The usual findings at MR imaging in
patients with Wernicke's encephalopathy include high signal intensities in the medial thalami and periaqueductal
regions of the midbrain. We describe a patient with acute Wernicke encephalopathy that showed a typical location of
hyperintense lesions on fluid-attenuated inversion recovery (FLAIR) and diffusion-weighted images.
CASE REPORT: A 78-year-old non-alcoholic woman was admitted to our department because of drowsiness, chest
pain and short of breath about 4~5 days. Head CT revealed only mild brain atrophy. On MR imaging, increased T2
signal of paraventricular regions of the thalamus and periaqueductal regions of the midbrain was observed. High-dose
thiamine therapy was started. The clinical condition improved gradually.
CONCLUSION: MR imaging is useful in early detecting and confirming the diagnosis of acute Wernicke's
encephalopathy when high-dose thiamine treatment can improve the prognosis of WE.
