Computed tomographic findings in childhood hemiplegia

Author and Disclosure Information


Childhood hemiplegias have been divided into two groups: congenital and acquired. The former group has also been referred to as the hemiplegie form of cerebral palsy. Either may have multiple etiologies.1 In 1933, Dyke et al2 described abnormalities in the skull roentgenograms of children with childhood hemiplegia. We have reviewed the computed tomographic (CT) scans in 54 patients with childhood hemiplegia and report the abnormalities found.

Case material

Fifty-four hemiplegie patients were studied retrospectively. Patients with severe bilateral involvement, brain tumors, progressive neurologic disorders, neurocutaneous syndromes, and hemiplegia of recent onset were excluded. The records of these excluded patients were reviewed.

All patients were interviewed and information concerning pregnancy, labor and delivery, birth weight, seizures, mental development, and possible etiologic factors was obtained. Pediatric and neurologic examinations followed. Results of psychometric testing, electroencephalograms (EEGs), skull roentgenograms, and contrast studies were reviewed.

CT scans without enhancement were obtained using the EMI scanner in 45 cases and the Delta Ohio Nuclear Scanner in nine cases. Sedation techniques varied and scans showing movement artifacts were excluded. CT scanning has been useful in defining intracranial structural abnormality.3


Thirty-four patients had congenital hemiplegia and 20 had the acquired form. The male to female ratio in both groups was similar. The average age of onset in the acquired group was 3 years and the average age at examination in both groups was 8 years. Prenatal and perinatal abnormalities were more frequent as expected in the congenital group. The right side was more frequently affected in . . .
