RESUMEN
@#ObjectiveTo study the characteristic findings on MRI in children surviving premature delivery with cerebral palsy.MethodsThe clinical data and MR imaging in 16 cases surviving premature delivery with cerebral palsy was retrospectively analyzed, compared with 16 healthy and age-matched controls.Results16 cases were final diagnosed as cerebral palsy with spstic diplegia. MRI features of children surviving premature delivery with cerebral palsy included abnormally high signal intensity in the periventricula white matter on T2WI, marked loss of periventricular deep white matter, ventriculomegaly with or without irregular ventricular outline and atrophy of the corpus callossum. These features were consistent with periventricular leukomalacia(PVL).ConclusionPVL was the characteristic findings on MRI in children surviving premature delivery with cerebral palsy. The characteristic findings of PVL was useful in determining the etiology and type of cerebral palsy in children.
RESUMEN
@#Objective To study the characteristic findings on magnetic resonance imaging (MRI) in children with cerebral palsy (CP) induced by chronic kernicterus.Methods The MR imagings in 13 CP cases induced by chronic kernicterus were retrospectively studied, which were compared with 6 healthy and age-matched controls. 13 cases were finally diagnosed as dyskinetic cerebral palsy (athetoid subtype).Results In 13 cases, all showed symmetric high signals in the the globus pallidus on T2-weighted imaging. There were not apparent abnormality on T1-weighted imaging.Conclusion The bilateral high intensity signals in the globus pallidus on T2-weighted imaging are the characteristic findings on MRI in CP children induced by chronic kernicterus. Paying attention to the globus pallidus on MRI may be useful in determining the type of cerebral palsy.
