- Eighteen children with right- and 13 with left-sided congenital hemiplegia were compared with 19 normal age-matched controls for verbal and non-verbal function. CT scans were obtained from 27 of the 31 hemiplegic children. The two hemiplegic groups were impaired in non-verbal function compared with controls. The right-hemiplegic group was more impaired in verbal function than the left-hemiplegic group and controls; however, impairments were restricted to the girls in the right-hemiplegic group. The results are discussed in terms of cerebral plasticity and functional reorganisation of cognitive functions after an early unilateral injury. It is argued that girls with left-hemisphere lesions may be more limited in cerebral plasticity than boys.

- Computed tomography (CT) of the brain has been used to evaluate potential etiologies of hemiplegic cerebral palsy in a population-based group of 28 children born preterm, in whom an obvious postnatal cause of hemiplegia could be excluded. The CT findings were classified according to a system so constructed to reflect the phase of brain maturation during which the insult causing hemiplegia likely had occurred. We found that 50% had evidence of periventricular leukomalacia the lesion typical of hypoxic-ischemic injury to the immature brain. However, it was not possible, neither from the CT scans nor from retrospective review of available clinical data, to date the injury more precisely to the pre- or perinatal period. Analysis of CT findings further showed that 18% of the children had cerebral maldevelopment, indicating an injury during early fetal life as the cause of hemiplegia, earlier than clinically suspected. The CT scans were normal in 25% of the children. It is concluded that the objective information obtained by studying the morphology of brain lesions using CT provides important information in addition to clinical data, and should be integrated with clinical assessment when attempts are being made to evaluate the etiology of cerebral palsy in children.

- CT brain scans were used to evaluate the most likely etiology of hemiplegic cerebral palsy in a group of children born at term. The population based study group comprised 83 children. The CT findings were classified to reflect the phase of brain maturation during which the injury causing hemiplegia most likely had occurred. The most common finding (37%) was periventricular atrophy considered to represent periventricular leukomalacia (PVL). PVL is a form of hypoxic-ischemic damage typical of the immature brain and most commonly seen as a complication of preterm birth. As this lesion was found in children born at term it was considered to reflect a cerebral injury that had occurred in utero. Cerebral maldevelopment, due to a very early intrauterine lesion, was detected in 17%, while cortical-/subcortical lesions, previously considered to be of major importance in hemiplegia, were seen in just 16% of the children. Altogether the CT findings indicated a prenatal origin of hemiplegia in 57%. Assessing the time of injury based on clinical records concurred with prenatal origin in 32% of the children thought to have prenatal origin of hemiplegia by CT. The objective information available from careful review of imaging information such as CT brain scans, is an important adjunct to clinical data. We propose that assessment of brain morphology, by means of imaging, should be integrated with clinical assessment when evaluating the etiology of brain lesions in children with congenital motor impairment.

Hemiplegic cerebral palsy: correlation between CT morphology and clinical findings.

- Morphological findings on CT were compared with clinical features of 111 children with hemiplegic cerebral palsy. Periventricular atrophy, interpreted as periventricular leukomalacia, was the most prevalent CT finding, although this type of lesion did not indicate severity of neurological impairment. Maldevelopments were associated with arm-dominated hemiplegia and with a wider range of clinical impairments than previously described. Cortical/subcortical atrophy, less common than presumed, indicated arm-dominated hemiplegia and was associated with more severe impairment than were other CT findings. A normal CT scan indicated leg-dominated hemiplegia and mild impairment. The morphological information obtained by CT was found to be useful for predicting clinical outcome, and was considered an important adjunct to clinical history and findings in these children.

- This study has analysed the results of CT scans of the brains in children with congenital hemiplegia. The material consists of 111 out of a total of 151 children with this cerebral palsy syndrome in a population-based series. We have classified the morphological findings in five groups. The groups are designed to reflect the phase of maturation of the brain when the insult happened. The groups are: 1. Maldevelopment, 2. Periventricular atrophy, 3. Cortical-/subcortical atrophy, 4. Miscellaneous, 5. Normal. In contrast to previous reports we found a high proportion (17%) with maldevelopment. However the dominating morphological pattern was periventricular atrophy, consistent with a hypoxic-ischemic insult to the immature brain, seen in 42%. Cortical and/or subcortical atrophy was found in 12%. Three children (3%) presented with morphological patterns not possible to classify. The group with no pathology according to CT was 26%.
