METHODS
A 37-year-old woman was admitted with total loss of vision of the left eye within 24 hours. Additionally, she complained about fatigue, headache, chills, fever, muscle pain and neck stiffness since 4 days. At admission, the body temperature was 38.7 degrees C. Neurological examination revealed papilledema and meningism.
METHODS
Ophthalmologic findings were consistent with a papillitis. The vision was lost, the pattern-shift checkerboard visual evoked potentials were not measurable. MRI of the brain and the optical nerve was without pathological findings, meningeal or cerebral Gadolinium enhancement was not present. The CSF analysis yielded a lymphocytic meningitis with 249 cells/mm (3), the glucose ratio of cerebrospinal fluid and serum was normal.
METHODS
The papillitis was treated unsuccessfully with high-dose methylprednisolone, the left eye remained blind. Persistence of the pleocytosis under initial treatment with aciclovir and ceftriaxone, reduction of the glucose ratio of cerebrospinal fluid and serum and intrathecal immunoglobuline A -- synthesis required a change of the diagnostic and therapeutic regimen. Various common and rare differential diagnoses were considered and ruled out, a chronic meningitis of unclear aetiology with the complication of amaurosis was diagnosed. In consideration of the most probable diagnosis, a tuberculostatic therapy was initiated. A prolonged reduction of the pleocytosis and normalization of cerebrospinal fluid parameters could be observed.
CONCLUSIONS
A large number of aetiologies can cause chronic meningitis; this case report reviews the most important differential diagnoses and highlights the limitations of the diagnostic work-up although various methods are available. Clinical course and symptoms of chronic meningitis are mild to moderate and may even be absent, but it can cause severe complications.
