INTRODUCTION
Aseptic meningitis is diagnosed using clinical and laboratory findings of meningeal inflammation in the absence of bacteria on the cerebrospinal fluid (CSF) smear and culture. It is commonly caused by a viral infection, and in most cases improves without specific treatment. Diagnostic clues for aseptic meningitis include positive meningeal sign tests, such as nuchal rigidity, jolt accentuation test, Kernig and Brudzinski sign, and specific CSF findings (such as elevated cell count and protein level, mildly decreased glucose level). In this case report, we present a case of aseptic meningitis in a 33-year-old Japanese man suspected of having the positive sign of ocular globe compression that was diagnosed only after repeated lumbar puncture.
