Abstract
Methotrexate (MTX)-induced leukoencephalopathy is the most often reported leukoencephalopathy following intrathecal or intravenous administration. A 72-year-old woman developed leukoencephalopathy localized to the cerebellum after treatment with oral MTX at a dose of 15 mg/week for 3 years. She complained of subtle imbalance during walking and reported having fallen. Her symptoms improved after discontinuation of MTX, and the leukoencephalopathy resolved. This is therefore a case report of selective cerebellar reversible leukoencephalopathy associated with oral MTX. Key Words: Leukoencephalopathy, Methotrexate, Cerebellum
