Thirty eight children with bilateral spastic cerebral palsy underwent MRI at the age of 5 years and more. Twenty nine showed correlates of periventricular leucomalacia, which were found especially in preterms (20 out of 21) but also in 9 of 15 fullterms without birth asphyxia. These findings suggest compromising events in the periand neonatal period especially in preterms and prenatal 3rd trimenon compromise in most of the fullterms without birth asphyxia.
