An 8
-year-old boy with leukemia in remission developed a meningitis-like syndrome associated with increased mononuclear cell count in the cerebrospinal fluid. Examination of the stained CSF sediment showed these to be small lymphocytes rather than lymphoblasts, suggesting a diagnosis of viral meningitis rather than leukemic infiltration of the meninges. Serologic studies gave evidence of a recent mumps virus infection. Viral meningitis should not be overlooked in the differential diagnosis of meningeal reactions in children with leukemia.
