Summary
Magnetic resonance imaging (MRI) is sensitive for diagnosing herpes simplex encephalitis (HSE) in children. Early white matter involvement on MRI is a common finding in HSE, and spinal MRI aids in diagnosing relapsed cases.
Area of Science:
- Pediatric Neurology
- Neuroradiology
- Infectious Diseases
Background:
- Herpes simplex encephalitis (HSE) is a severe neurological condition in infants and children.
- Accurate and timely diagnosis is crucial for effective management and improving outcomes.
Purpose of the Study:
- To evaluate the utility of magnetic resonance imaging (MRI) in diagnosing HSE in pediatric patients.
- To identify common MRI findings associated with HSE, including early white matter changes and potential spinal cord involvement.
Main Methods:
- Retrospective analysis of brain and spinal MRI scans from 7 pediatric patients diagnosed with HSE.
- Review of T1- and T2-weighted imaging for lesion characteristics, locations, and temporal evolution.
Main Results:
- Common MRI findings included hypointense and hyperintense gray and white matter areas, particularly in the temporal lobes.
- Hemorrhagic lesions were observed in 57% of patients.
- Early white matter involvement, detectable as early as day 4, was a frequent finding.
- One patient with relapsed encephalomyelitis showed diffuse T2 hyperintensities on spinal MRI.
Conclusions:
- MRI is a sensitive diagnostic tool for pediatric HSE.
- Early white matter involvement on MRI is a significant finding in HSE.
- Spinal MRI can be valuable in diagnosing relapsed herpes simplex encephalomyelitis.
