In order to examine the cranial CT of autistic children and investigate the etiological significance of CT scan findings, the CT of the brain was surveyed in 24 children with early infantile autism (3 to 17 years with a mean age of 7.6), and 179 children with the normal CT despite their medical histories such as headaches or febrile convulsions. According to their ages, the autistic and normal children were divided into the following three groups: Group I (age ranging from 3 to 5), Group II (age: 6 to 9) and Group 111 (age: 10 to 17). 1) There was no significant difference between the bifrontal CVI of the autistic children and that of the normal children. However, in Group III, the bifrontal CVI of the autistic children was significantly higher than that of the normal children. 2) There was no significant difference between the bicaudate CVL of the autistic children and that of the normal children. However, in Groups I and II, the bicaudate CVI of the autistic children was significantly lower than that of the normal children. 3) The maximum widths of the third ventricle showed no significant difference between the autistic and normal children. However, in Groups II and III(, those of the autistic children were wider than those of the normal children. In the autistic children, as the age increases, the difference becomes significantly wider. A positive correlation was observed between the width of the third ventricle and ages of the autistic children. 4) An examination of the right‐left ratio of maximum transverse diameter of the brain showed that there was no significant difference between the autistic and normal children. The above‐mentioned results (1)‐4)) might suggest a progressive disorder of the brain structure surrounding the third ventricle or lateral ventricles in the autistic children.
