Optic Chiasm Involvement With Concurrent Typical Wernicke Encephalopathy Magnetic Resonance Findings: A Case Report.

The variable clinical presentation of Wernicke encephalopathy often complicates interpretation. Prompt and accurate diagnosis relies on a constellation of typical and atypical magnetic resonance imaging (MRI) findings, which are not always simultaneously present. Our case demonstrates concurrent presentation of all typical Wernicke encephalopathy MRI findings with additional signal abnormalities involving the optic chiasm and optic tract. We suggest that optic pathway involvement may be considered among several atypical MRI manifestations, reinforcing the prompt diagnosis of the potentially life-threatening encephalopathy.
