Wernicke's encephalopathy: atypical manifestation at MR imaging

S J Bae et al. AJNR Am J Neuroradiol. 2001 Sep.

Abstract

We report a case of atypical manifestation of hyperintense lesions in a 64-year-old female patient with Wernicke's encephalopathy. Fluid-attenuated inversion recovery and T2-weighted images demonstrated symmetrical distribution of hyperintense lesions in cerebellar dentate nuclei, tegmentum of the lower pons, red nuclei, and tectum of the midbrain, and T1-weighted sagittal images showed atrophy of the mamillary bodies. The hyperintense lesions were completely resolved on follow-up MR images.

May 29. A–C, FLAIR axial images. A, Red nuclei of the midbrain are hyperintense compared with the brain parenchyma (solid arrows). White matter hyperintensity (open arrow) adjacent to the dilated right lateral ventricle is probably a change due to the abscess cavity. B, Tectum of the midbrain also shows symmetric hyperintensities (arrows). C, At the lower pons level, symmetrical hyperintense lesions are also detected in facial nuclei (solid arrows), vestibular nuclei (open arrows), and abducens nuclei (arrowheads) of the pontine tegmentum and cerebellar dentate nuclei (double arrows). D, T1-weighted sagittal image shows atrophy of mamillary body (arrow).
