Background:
Brain MRI is a useful tool for diagnosing inflammatory demyelinating disorders in children. However, it remains unclear which are the most reliable criteria for distinguishing multiple sclerosis (MS) from monophasic disorders such as acute disseminated encephalomyelitis (ADEM). We therefore compared the 4 current sets of MRI criteria in our Dutch pediatric cohort and determined which are the most useful in clinical practice for distinguishing ADEM from MS.
Methods:
We included 49 children who had had a demyelinating event and an MRI scan within 2 months of their first clinical attack. Twenty-one patients had ADEM and remained relapse-free after at least 2 years of follow-up. Twenty-eight patients had a definitive diagnosis of MS. We assessed the sensitivity and specificity of the following MRI criteria: Barkhof criteria, KIDMUS criteria, Callen MS-ADEM criteria, and Callen diagnostic MS criteria.
Results:
The Callen MS-ADEM criteria had the best combination of sensitivity (75%) and specificity (95%). The KIDMUS criteria had higher specificity (100%), but much lower sensitivity (11%). The Barkhof criteria had a sensitivity of 61% and a specificity of 91%. The Callen diagnostic MS criteria were the most sensitive (82%), but were only 52% specific for distinguishing a first attack of MS from ADEM.
Conclusions:
The results in our cohort demonstrate that the new Callen criteria for multiple sclerosis-acute disseminated encephalomyelitis (MS-ADEM) are the most useful for differentiating a first attack of MS from monophasic ADEM. Although the Callen diagnostic MS criteria are more sensitive, they lack the specificity necessary to differentiate MS from ADEM.
Insights
The Callen MS-ADEM MRI criteria best distinguish pediatric multiple sclerosis (MS) from acute disseminated encephalomyelitis (ADEM), offering high specificity and sensitivity for accurate diagnosis in children.
Area of Science:
- Pediatric Neurology
- Neuroimaging
- Demyelinating Diseases
Background:
- Brain MRI is crucial for diagnosing pediatric inflammatory demyelinating disorders.
- Distinguishing multiple sclerosis (MS) from acute disseminated encephalomyelitis (ADEM) in children using MRI remains challenging.
- Current MRI criteria require validation for clinical utility in pediatric demyelinating disease differentiation.
Purpose of the Study:
- To compare the diagnostic performance of four sets of MRI criteria.
- To identify the most reliable MRI criteria for differentiating pediatric MS from ADEM.
- To assess the sensitivity and specificity of Barkhof, KIDMUS, Callen MS-ADEM, and Callen diagnostic MS criteria.
Main Methods:
- Retrospective analysis of 49 pediatric patients with demyelinating events and early MRI.
- Inclusion of patients with confirmed ADEM (n=21) or MS (n=28) based on long-term follow-up.
- Systematic assessment of Barkhof, KIDMUS, Callen MS-ADEM, and Callen diagnostic MS criteria performance.
Main Results:
- Callen MS-ADEM criteria demonstrated optimal performance with 75% sensitivity and 95% specificity.
- KIDMUS criteria showed 100% specificity but only 11% sensitivity.
- Barkhof criteria yielded 61% sensitivity and 91% specificity.
- Callen diagnostic MS criteria were most sensitive (82%) but least specific (52%).
Conclusions:
- The Callen MS-ADEM criteria are highly effective for differentiating pediatric MS from monophasic ADEM.
- While sensitive, the Callen diagnostic MS criteria lack the specificity needed for accurate MS vs. ADEM differentiation.
- These findings support the clinical utility of Callen MS-ADEM criteria in pediatric neuroinflammatory disease diagnosis.
