Herpes simplex encephalitis (HSE) can present with normal initial cerebrospinal fluid (CSF) findings, delaying diagnosis. Early consideration of HSE in encephalopathic patients is crucial, even with a normal CSF analysis, to prevent severe outcomes.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Virology

Background:

  • Herpes simplex virus (HSV) is a frequent cause of viral encephalitis.
  • Herpes simplex encephalitis (HSE) typically manifests with acute neurological changes.
  • Cerebrospinal fluid (CSF) analysis is almost invariably abnormal in typical HSE presentations.

Observation:

  • This report details a case of HSE in a patient with an initially normal CSF examination.
  • The normal initial CSF analysis contributed to a delay in diagnosis and treatment.
  • This delay led to severe neurological sequelae in the patient.

Findings:

  • A normal initial CSF examination does not exclude the possibility of Herpes simplex encephalitis.
  • Delayed diagnosis of HSE can result in significant and potentially irreversible neurological damage.

Implications:

  • Herpes simplex infection must be considered in the differential diagnosis of encephalopathic patients, irrespective of CSF findings.
  • Clinicians should maintain a high index of suspicion for HSE even when initial CSF results are unremarkable.
  • Prompt recognition and treatment of HSE are essential to mitigate severe neurological sequelae.
