Magnetic resonance imaging in diplegic form of cerebral palsy

Area of Science:

• Neuroimaging
• Pediatric Neurology
• Ophthalmology

Background:

• Cerebral palsy (CP) is a common neurodevelopmental disorder.
• Enlarged occipital horns of lateral ventricles are noted in some CP cases.
• Squint (strabismus) is a frequent comorbidity in children with CP.

Purpose of the Study:

• To compare the efficacy of MRI and CT in visualizing white matter lesions in children with diplegic CP.
• To investigate the association between occipital white matter lesions and squint in CP.
• To establish the diagnostic superiority of MRI for CP-related neuroimaging.

Main Methods:

• Retrospective analysis of 18 children with diplegic CP.
• Comparison of MRI (FLAIR and TSE T2-weighted) with CT scans.
• Correlation of neuroimaging findings with the presence of squint.

Main Results:

• MRI detected white matter lesions in occipital areas in all patients with squint (16/18).
• CT scans failed to detect these lesions retrospectively.
• MRI demonstrated clear superiority over CT in visualizing subtle white matter changes.

Conclusions:

• MRI is the preferred imaging modality for evaluating white matter abnormalities in children with CP, especially when squint is present.
• Occipital white matter lesions may underlie impaired visual coordination leading to squint in CP.
• Neuroimaging findings highlight potential etiological links between brain lesions and visual deficits in CP.
