Summary
This case highlights an unusual presentation of herpes simplex virus-2 (HSV-2) meningitis mimicking idiopathic intracranial hypertension (IIH). Elevated intracranial pressure and papilledema were observed, with HSV-2 confirmed via PCR in cerebrospinal fluid.
Area of Science:
- Neurology
- Infectious Diseases
- Ophthalmology
Background:
- Idiopathic intracranial hypertension (IIH) typically presents with headache, visual disturbances, and papilledema.
- Cerebrospinal fluid (CSF) analysis in IIH usually shows normal or mildly elevated protein and cell counts.
- Viral meningitis can cause elevated intracranial pressure, but papilledema is not a commonly described feature.
