Excessive accumulation of CSF was found in the supratentorial intracranial extracerebral space of many infants by means of computerized tomography. CT head scanning was carried out 220 times in 153 clinically normal infants during the last year. The accumulation was most notable in the bifrontal convexity space, bitemporal convexity space, interhemispheric cistern, suprasellar cistern and Sylvian cistern. The space was not remarkable in new-born infants, but soon began to expand gradually until the infant became four months of age. The space was most remarkable four to seven months after birth. Then, the space decreased in volume gradually and disappeared between twelve and eighteen months of age, without any developmental, neurological or psychological troubles. Accidents during the fetal or delivery periods did not notably influence the with of the space. This phenomenon may be regarded as a physiological state in early infancy.
