Method: The subjects comprised 83 patients with CP. We analyzed the brain MRI findings such as periventricular leukomalacia (PVL), brain atrophy, infarction or hemorrhage, basal ganglia lesion, migration anomaly and delayed myelination with consideration of clinical subtypes of CP.

Results
: Of the 83 MRI findings, 69 abnormalities (83.1%) were the followings; PVL in 47 cases{17 spastic diplegics (SD), 17 spastic quadriplegics (SQ), 5 spastic hemiplegics (SH), 4 atonic or hypotonic quadriplegics, 2 ataxic quadriplegics and 2 mixed quadriplegics (MQ)}, brain atrophy in 6 cases (3 SQ, 1 SD, 1 SH and 1 MQ), infarction or hemorrhage in 7 cases (5 SH and 2 SQ), migration anomaly in 2 cases (1 SQ and 1 SH), delayed myelination in 3 cases (2 SQ and 1 SH) and basal ganglia lesion in 4 cases (3 MQ and 1 atonic quadriplegic). 33 cases of 47 PVL and 2 cases of 6 brain atrophy were preterm CPs. There was no difference in severity of CP between preterm and fullterm CPs.

Conclusion
The results of this study would be helpful in estimating the brain lesions in various clinical subtypes of CP. (J Korean Acad Rehab Med 2003; 27: 862-867)
