Computerized axial tomography in the preoperative evaluation of posterior fossa tumors in children.
22 cases of pediatric posterior fossa tumors that underwent preoperative evaluation by computerized tomography are presented. 8 of the cases, in the latter part of the series, were successfully operated upon on the basis of computerized tomography alone. In 14 other cases, additional angiographic investigation was carried out. In only 1 case of multiple hemangioblastoma did angiography provide further significant information. On the basis of this experience, it is suggested that computerized tomography is usually sufficient and further contrast studies are unnecessary in the preoperative evaluation of pediatric posterior fossa tumors.
