Nonalcoholic Wernicke Encephalopathy in a Pediatric Patient with a History of Medulloblastoma

A 14-year-old girl with medulloblastoma resected 3 years earlier presented with altered mental status, dysarthria, and tremors and was ultimately diagnosed with Wernicke encephalopathy. While Wernicke encephalopathy is associated with alcoholism, it is also seen in the pediatric population, in which imaging findings may be atypical. Furthermore, Wernicke encephalopathy is likely underdiagnosed in the pediatric population, particularly in high-risk groups, such as chronically ill children or children with underlying malignancy.
