In order to examine if specific findings from CT correlate with specific clinical or neurological findings, 30 children, 5 to 16 years old, born at term, affected by congenital hemiparesis without intellectual impairment, were submitted to neurofunctional and psychological assessment and examined by CT. 28 of the 30 children had pathological CT. Two morphological CT patterns were found: A) Cavity in the cortex and underlying subcortical white matter (11 cases); B) Unilateral ventricular enlargement and paraventricular lesions (17 cases). CT was normal in two cases. In our children, born at term, no statistical correlation between CT patterns and anamnestic data was found as described in other studies, although in the patients with cortical-subcortical lesions, there was a slight prevalence of a history of perinatal complications, and in the patients with paraventricular lesions there was an uneventful history or abnormal pregnancy history. The relation between specific CT patterns (type A and B) and specific clinical dysfunction is not statistically evident, (unless for astereognosis and type A CT pattern). However, the patients with cortical-subcortical lesions showed a slight prevalence of a lower function of the impaired hand, and a higher percentage of an I.Q. of <90, than the group with unilateral ventricular enlargement. No relation was found between CT lesional pattern and epilepsy. The absence of correlation between morphological aspects and clinical findings could be explained by the complexity of structural changes and remodelling properties of the central nervous system, following prenatal and perinatal brain damage.
