Intrathecal methotrexate-induced acute cerebellar syndrome

Abstract

Intrathecal application of chemotherapeutics has been the mainstay of central nervous system prophylaxis in acute lymphoblastic leukemia treatment. We describe a patient who developed acute cerebellar syndrome after prophylactic intrathecal methotrexate administration and recovered spontaneously. To our knowledge, this is the first case of methotrexate-related acute cerebellar syndrome.
