Abstract:
Twenty four pediatric migraineurs were prospectively evaluated to determine if white matter hyperintensities were present on magnetic resonance imaging (MRI). None had white matter findings or brain abnormalities. Five had mucoperiosteal thickening of the paranasal sinuses, which were unrelated to the patients' clinical course. MRI white matter findings are probably not a common occurrence in pediatric migraineurs. In addition, MRI sinus findings are not necessarily related to a child's headache complaints.
Insights
Pediatric migraineurs rarely show white matter changes on MRI scans. Sinus abnormalities found on imaging may not be linked to a child
Area of Science:
- Neurology
- Pediatrics
- Radiology
Background:
- Migraine is a common neurological disorder in children.
- The role of neuroimaging in pediatric migraine diagnosis is under investigation.
- White matter hyperintensities and sinus abnormalities are potential findings on MRI.
Purpose of the Study:
- To prospectively evaluate pediatric migraineurs for white matter hyperintensities on MRI.
- To assess the prevalence of brain abnormalities in this population.
- To determine the clinical relevance of sinus findings in pediatric migraine.
Main Methods:
- Prospective evaluation of 24 pediatric migraineurs.
- Magnetic resonance imaging (MRI) was used to assess brain structure.
- Clinical course and imaging findings were correlated.
Main Results:
- No white matter hyperintensities or brain abnormalities were detected in any patient.
- Five patients (20.8%) exhibited mucoperiosteal thickening of the paranasal sinuses.
- Sinus findings were not associated with the patients' clinical course or headache severity.
Conclusions:
- White matter hyperintensities are likely uncommon in pediatric migraineurs.
- Incidental MRI findings of the paranasal sinuses may not be directly related to pediatric headache complaints.
- Routine MRI for pediatric migraine may not be indicated solely for detecting white matter changes or sinus disease.
