Summary
Chronic herpes simplex virus encephalitis is rare in children. This case highlights diagnosis using PCR and CSF analysis, with prolonged antiviral therapy improving outcomes.
Area of Science:
- Neurology
- Virology
- Pediatrics
Background:
- Herpes simplex virus (HSV) is a common cause of acute encephalitis in children.
- Chronic forms of HSV encephalitis are exceptionally rare, posing diagnostic challenges.
Observation:
- A 6-year-old female presented with symptoms suggestive of chronic encephalitis.
- Diagnostic workup included polymerase chain reaction (PCR) for HSV DNA, CSF analysis for HSV-specific IgG, and neuroimaging.
Findings:
- Diagnosis confirmed by detecting HSV DNA in cerebrospinal fluid (CSF).
- Elevated CSF/serum ratio of HSV-specific IgG and oligoclonal IgG bands in CSF supported the diagnosis.
- Cerebral CT scan revealed calcifications in the temporal regions.
Implications:
- Early and accurate diagnosis of chronic HSV encephalitis is crucial.
- Prolonged antiviral treatment can positively impact neurodevelopmental outcomes in affected children.
- This case underscores the importance of considering chronic HSV encephalitis in pediatric neurological disorders.
