Abstract:
We report on two children with acute encephalopathy showing mild clinical manifestations and reversible white matter lesions. In both patients, MRI revealed high intensities on T (2)-weighted imaging and marked reductions of water diffusion in the white matter of the bilateral centrum semiovale and the corpus callosum. These abnormalities disappeared along with the neurological symptoms within a week in both patients. These children represent a characteristic group of patients among childhood acute encephalopathy.
Insights
Two children with mild acute encephalopathy showed reversible white matter lesions on MRI. Neurological symptoms and brain imaging abnormalities resolved within one week, highlighting a unique patient group.
Area of Science:
- Neurology
- Pediatrics
- Radiology
Background:
- Acute encephalopathy in children can present with diverse neurological symptoms and imaging findings.
- Understanding the spectrum of white matter abnormalities is crucial for diagnosis and prognosis.
Observation:
- Two pediatric patients presented with mild acute encephalopathy.
- Magnetic Resonance Imaging (MRI) revealed characteristic white matter signal changes.
Findings:
- High signal intensities on T2-weighted imaging and restricted diffusion were observed in the centrum semiovale and corpus callosum.
- These MRI findings and neurological symptoms were completely reversible within one week.
Implications:
- This case series identifies a distinct subgroup of childhood acute encephalopathy with reversible white matter lesions.
- The findings suggest a favorable prognosis for patients with this specific MRI pattern.
