Brain Tumors In Children With Normal Skull Roentgenograms

T HE skull roentgenograms ofo con- secutive children with proven brain tu- mors were reviewed because the reported incidence of bony calvarial abnormalities of 70-80 per cent in retrospective studies seemed high.24 The purpose of this study is to emphasize the need for further neuroradiographic pro- cedures despite normal skull roentgeno- grams if the signs and symptoms suggest a neoplasm. The possible reasons for the dif- ference between the findings in this series and those found in the literature are dis- cussed.
