Unusual presentation of aseptic meningitis.

The CSF cell count in aseptic meningitis is characteristically in the range of 10 to 500/cu mm, and in most cases, below 1,500/cu mm. This 25-year-old woman had a CSF cell count of up to 7,780/cu mm. However, the diagnosis of aseptic meningitis seemed to be well established by the complete disappearance of signs and symptoms after only symptomatic treatment.
