[Some characteristic features of RI-cisternography in infancy and childhood (author's transl)].
There are few reports which discussed normal RI-cisternography in infancy and childhood. The cisternograms of the children between 2 months and 13 year-old were classified under a criteria into three groups; 17 normal cases, 135 borderline cases and 77 abnormal cases. The former two groups were compared with each other and characteristic findings of RI-cisternography in infants and children were appreciated clinically. And we attempted to establish normal RI-cisternography. The characteristic findings are: 1) When the images of cisterna magna is dilated, it can not be concluded directly that the abnormality of posterior fossa are suspected. 2) The bulk flow of CSF in infancy and childhood flows faster in intracranial subarachnoid space as well as intraspinal than the flow of adults. 3) Early ventricular reflux seems to be not valuable clinically. But we would like to emphasize that the incidence of these findings are variable as children grow older. The mechanism of this phenomenon needs further investigation.
