Magnetic resonance imaging in diplegic form of cerebral palsy.

Eighteen children with diplegic form of cerebral palsy (CP) underwent magnetic resonance imaging (MRI) because of the enlarged occipital horns of both lateral ventricles found on previous computerized tomography (CT). In 16 of them squint was present. MRI in flow attenuated inversion recovery (FLAIR) and turbo spin echo (TSE) modes (T2 weighted images) best showed white matter lesions in occipital areas in all patients with squint, while no white matter changes could be detected in CT (in retrospect), thus proving the superiority of MRI in examining CP children. The authors postulate that the hemispheric occipital lesion causing impairment of visual co-ordination may result in squint.
