Abstract
Brain scintigraphy is a simple, innocuous and valuable diagnostic method. Particularly in child-ren, in order to minimize the damage by examina tion, brain scintigraphy shoud be the first exa-mination for the patients prior to other diagno-stic methods such as cerebral angiography and pneumoencephalograhy.
For the past 3 years, between Jan. 1970 and Dec. 1972, 235 children under the age of 15 years had brain scintigraphy with Tc-99 m pertechne-tate at the Tokyo Women's Medical College Hospital.
We especially attended to the findings of scinti-grams in children with hydrocephalus.
Children with non-neoplastic hydrocepalus scanned with Tc-99 m pertechnetate were 29 cases.

In noncommunicating hydrocephalus, the mid-line structure on the scintigram appeared thicker than the normal, because activity in the superior sagittal sinus was relatively high comparing to reduction of activity in the enlarged ventricles.
In cases of very severe hydrocephalus, the basal ganglia was shown as clear hot spot on the scintigram, becauseR.I. activity in the basal ganglia was relatively high comparing to reduc-tion of R. I. activity in the enlarged ventricles.
In cases of hydroencephalodysplasia, the mid-line structure on the scintigram shifted to the side opposite to the dysplasia, resulting from pressure with a large CSF collection.
In cases of cranium bifidum, the scintigram showed an elevation of the transverse sinus and confluent sinus.
