THE ASEPTIC-MENINGITIS SYNDROME - A COMPLICATION OF POSTERIOR-FOSSA SURGERY

The syndrome of aseptic meningitis is characterized by spiking fever and meningismus. CSF analysis generally shows increased pleocytosis, hypoglycorrhachia, elevated protein and negative cultures. In an earlier series, 70% of children with posterior fossa operations developed the syndrome. In a new review the incidence was slightly more than 30%. The incidence of aseptic meningitis following operation for structural lesions was 44%, which was higher than the tumor group, where the meningitic syndrome was seen in 25% of the children. It is the purpose of this paper to reexamine the impact that steroids have made on the prevalence of the aseptic meningitis syndrome, and to review recent studies that have attempted to distinguish between aseptic and bacterial meningitis.
