An 80-year-old man with squamous cell carcinoma developed TRE precipitated by systemic infection in the context of three weeks of dysphagia. Antibiotic treatment did not reverse his cognitive symptoms, and a diagnosis of TRE was made based on operationalized criteria. Thiamine 100 mg IV daily did not reverse his symptoms. On his 30th day of admission, thiamine was increased to 500 mg IV t.i.d., resulting in a rapid reversal of altered mental status.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951514001163_sec4\"><jats:title>Significance of Results:<\/jats:title><jats:p>This report adds to the list of cancer types in which TRE\/Wernicke's encephalopathy has been reported.
