Brain MRI findings were analyzed in 30 patients with clinical cerebral palysy to determine clinical role in assessment of time of brain damage. The patients (1 day to 14 yrs. old) underwent MR scanning and findings were correlated with clinical
history
retrospectively.
Among 13 prematurely born patients. 11 cases showed abnormal findings in brain MR, which were periventricular leukomalacia in 10 patients and cortical gray matter disease in 1 patient. And MR scans of 17 patients born at or around the expected
date
of
confinement were reviewed. Fifteen cases showed anormal findings in MR, which are, cortical gary matter disease in 10 patients, deep white matter lesion in 3 patients and neuronal migration anomaly such as schizencephaly, polymicrogyria and
pachygyria
in 3 patients.
Abnormality in contour of ventricle in prematurely born patients were dilatation of trigone & irregular ventricular contour in 4 patients and diffuse enlargement in 3 patient. Among patients born at term, dilatation of trigone & irregular
ventricular
contour in 3 patients and diffuse enlargement in 6 patients were observed.
Corpus callosal abnormalities were thinning of posterior body in 7 patients, diffuse thinning in one patient and irregularity in 4 patients among the prematurely born and thinning of posterior body in 9 patients, diffuse thinning in 2 patients,
abscent
in 1 patient and irregularity in 3 patients among the patients born at term.
MR imaging seemed to be very useful in determining the time of the insult which could have been the cause of the cerebral palsy.
