METHODS: Questionnaires were mailed to the leading neonatal intensive care units (NICU) and rehabilitation centers for children. RESULTS: The incidence of PVL in the group of surviving preterm infants of gestational ages less than 33 weeks was 4.8-4.9\% on ultrasound and 7.7-7.9\% on magnetic resonance imaging and/or computed tomography. The incidence of PVL did not decrease between 1990 and 1994. The incidence of PVL in the NICU varied from 0 to 47.1\%. Infants from multiple pregnancies had a higher incidence (9.1\%) of PVL than those from single pregnancies (6.2\%). The proportion of PVL in all patients in rehabilitation centers with cerebral palsy (CP) has increased recently. CONCLUSIONS: It was roughly calculated that about 750 cases of CP with PVL occurred annually in Japan, thus accounting for about one-third of the total number of cases of CP.
