A 9-year-old girl developed meningitis after posterior craniotomy and ventriculoperitoneal shunt placement for management of a right-sided cerebellar pilocystic astrocytoma. Initial concerns included postoperative meningitis or shunt infection, but multiple cultures of cerebrospinal fluid were sterile, and she did not respond to antibacterial therapy. Aseptic or chemical meningitis (although uncommon and rarely reported) was considered, and treatment with dexamethasone was curative.
