Brain MRI detection of early Wernicke's encephalopathy in a hemodialysis patient.

A 93-year-old hemodialysis patient became hospitalized for thiamine deficiency-induced appetite loss and ultimately experienced consciousness disorder diagnosed as Wernicke's encephalopathy (WE). Since brain MRI on admission was retrospectively found to display faint WE findings, careful brain MRI assessment is recommended in hemodialysis patients with appetite loss alone.
