[Periventricular leukomalacia: its retrospective diagnosis in children with spastic diplegia].
Typical images of residual periventricular leukomalacia (PVL) have been searched for in a review of the CT scans of 135 children with spastic diplegia. Among the 135 children studied, 90 (66.6%) of them had had a CT scan with 51 (56.6%) showing typical images of residual PVL. Only 6 (11.7%) of these 51 children were identified in the early stages by cranial ultrasound and 11 (21.5%) of the 51 were diagnosed by CT scan. The remaining 34 (66.6%) were diagnosed retrospectively during our study and none of them were identified as PVL in the first examination by CT scan. In addition to CT scan examination, 3 children were explored by MRI that confirmed the diagnosis of PVL. The results of our study indicate that images in CT scans reported as slight ventricular dilation, normotensive hydrocephalus, hydrocephalus with irregular limits, subcortical atrophy or periventricular heterotopia could corresponds to images of residual PVL in the appropriate context. We emphasize the importance of CT scan examination for the retrospective diagnosis of PVL in elder children in which cranial ultrasound examination had not been performed during the neonatal period.
