To the Editor: The report of the European Cerebral Palsy Study by Dr Bax and colleagues1 confirms that spastic diplegia is the most common form of CP in premature infants, and establishes that periventricular leukomalacia (PVL) is the most common pathology. However, about 8% of children with spastic diplegia have normal MRI results, and 25% of children with PVL on MRI do not have any neurological disorder.2 There is thus a poor correlation between MRI and clinical findings.
