“…This is in accordance with previous reports. 21,22 In patients with spastic tetraplegia, periventricular leukomalacia, cerebral atrophy, and congenital brain anomalies were the most frequent abnormalities in the present study. In contrast to earlier reports, 5,8 congenital brain anomalies were detected in only 13.3% of patients with tetraplegic cerebral palsy.…”

A prospective study was undertaken of 129 children with spastic cerebral palsy to clarify the relationship between magnetic resonance imaging (MRI) findings and clinical features of cerebral palsy. Low birth weight, asphyxia, prematurity, seizures, mental development, Gross Motor Function Classification System, and MRI findings were analyzed. Significant abnormalities relevant to the cerebral palsy were evident on imaging in 123 (95.3%). A similar percentage of MRI abnormalities were detected in the groups, 45 (100%) in patients with tetraplegic cerebral palsy, 37 (92.5%) in children with diplegic cerebral palsy, and 42 (95.4%) with hemiplegic cerebral palsy. Periventricular leukomalacia was detected more frequently in the children with spastic diplegia than in the patients with tetraplegia or hemiplegia. Cerebral atrophy was found more often in the tetraplegic group compared to the diplegic patients. Porencephalic cysts were detected more frequently in children with spastic hemiplegia. Congenital brain anomalies were found in a higher proportion in tetraplegic children. Significant correlations between the MRI findings and Gross Motor Function Classification System in the diplegic and tetraplegic patients were found. No correlations between the MRI results and risk factors for cerebral palsy in the tetraplegic patients were noted. Early detection of brain abnormalities in children with cerebral palsy may help in the prognosis and in the initiation of appropriate therapy

“…It is likely that many of the infants enrolled in the other studies were not scanned for a sufficient length of time as a result of early discharge or because further scans were not deemed necessary because of initial normal US scan findings. [11][12][13][14] We have great concern about the recommendations given in two recent studies. One suggests that there is no need for further US scans when two normal US examinations, at least 7 days apart, have been obtained, in the absence of any further clinical deterioration.…”

“…22,23 However, if only one or two early or late cUS scans are performed, the detection of cystic PVL, the most predictive cUS marker for CP, is less reliable. 24 The infrequent scanning protocol recommended by the American Academy of Neurology is of concern. 25 In a excellent study by de Vries et al assessing cUS in high-risk preterm infants, highresolution, sequential cUS showed abnormalities in the majority (94%) of children having CP by 2 years.…”

Cranial ultrasound (cUS) provides bedside imaging access to the neonatal brain. Modern scanners and the use of various acoustic windows give detail not only of the well known pathologies met in the preterm infant, but also allow assessment of more subtle aspects of normal and abnormal brain growth and development. cUS is also very helpful in the early diagnosis of the many aetiologies of neonatal encephalopathy and seizures in the term infant and the subsequent monitoring of progress of hypoxic-ischaemic brain injury. Training issues in cUS need to be addressed.
