Herpes simplex virus type 1 encephalitis can present with confusing symptoms and non-specific CT scans, mimicking pneumonia or stroke. Early recognition is crucial to prevent severe outcomes from this viral brain infection.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Radiology

Background:

  • Viral encephalitis poses significant risks, with delayed diagnosis leading to severe morbidity and mortality.
  • Herpes simplex virus type 1 (HSV-1) is a common cause of sporadic fatal encephalitis.
  • Prompt diagnosis and management are critical for improving patient outcomes.

Observation:

  • A case of HSV-1 encephalitis presented with confusion, speech difficulties, and fever.
  • Initial brain CT scans showed non-specific findings.
  • These early signs mimicked more common conditions like pneumonia with stroke.

Findings:

  • The non-specific early clinical and CT findings of HSV-1 encephalitis can lead to misdiagnosis.
  • Differential diagnosis should include HSV-1 encephalitis even with atypical presentations.

  • Radiological and clinical correlation is essential for accurate and timely diagnosis.

    • Implications:

    • Increased awareness of HSV-1 encephalitis is needed among emergency physicians and radiologists.
    • Early consideration of HSV-1 encephalitis can prevent diagnostic delays.
    • Timely treatment initiation is vital for reducing morbidity and mortality associated with HSV-1 encephalitis.
