Summary
A child developed encephalitis following chickenpox (varicella). Imaging revealed cerebellar edema and demyelination, confirming varicella encephalitis in this rare case.
Area of Science:
- Neurology
- Pediatrics
- Infectious Diseases
Background:
- Varicella (chickenpox) is a common viral infection, typically mild in children.
- Encephalitis is a rare but serious complication of varicella infection.
- Cerebellar involvement in post-varicella encephalitis is known, but focal edema is less commonly highlighted.
Observation:
- A 4-year-old boy presented with symptoms of encephalitis two weeks after chickenpox onset.
- Neuroradiologic imaging, including CT and MRI, showed cerebellar edema and demyelination.
- Cerebrospinal fluid analysis confirmed the diagnosis of varicella encephalitis.
Findings:
- This case represents the first reported instance of focal cerebellar edema associated with clinical varicella infection.
- The neuroradiologic findings of cerebellar edema and demyelination were consistent with encephalitis.
- Diagnostic confirmation was achieved through cerebrospinal fluid titers.
Implications:
- Highlights the potential for focal cerebellar edema as a manifestation of varicella encephalitis in children.
- Emphasizes the importance of advanced neuroimaging in diagnosing and understanding rare neurological complications of viral infections.
- Contributes to the understanding of the spectrum of central nervous system involvement in varicella.
