We review the clinical courses and outcomes of an outbreak of enteroviral infection that occurred in 5 children with acute lymphoblastic leukemia during a 2-month period in a hematology-oncology unit. Three patients presented with encephalitis and 2 with parotitis. Three of the 5 patients recovered uneventfully and 2 died, 1 of chronic encephalitis and 1 of acute brain stem encephalitis.
