Wernicke’s Encephalopathy: Typical Disease with an Atypical Clinicoradiological Manifestation

Abstract

AbstractWernicke’s encephalopathy is an acute neurological disorder caused due to thiamine deficiency. It is characterized by a triad of confusion, ataxia, and ophthalmoplegia. Wernicke’s encephalopathy can present with atypical clinical manifestations, particularly in setting of nonalcoholic background. Our patient manifested with clinical complaints of acute drowsiness, speech difficulty, and ataxia. Magnetic resonance imaging of the brain revealed T2 hyperintensity in bilateral medial thalami, globus pallidus, periaqueductal gray matter, dorsal pons, and dorsal medulla. The diagnosis of Wernicke’s encephalopathy was entertained and he well responded to parental thiamine therapy. The clinician should be aware about atypical presentation of Wernicke’s encephalopathy.
