Computerized transaxial tomography (CTT) is a noninvasive roentgenologic method that demonstrates the configuration of the intracranial contents, including the cerebral parenchyma and the ventricular system. Of 207 children examined by CTT, 53 later had neuroradiologic contrast studies or neurosurgical intervention, or both, and two came to autopsy. The neuroradiologic, surgical, and pathologic findings corresponded with the CTT findings in patients with large ventricles, supratentorial tumors, intracranial hematomas or cysts, and epidural collections. The correlation was less concordant in patients with intracranial vascular malformations or lesions involving cranial bones. CTT promises to be valuable for diagnosis of many intracranial lesions in children.
Presented in part at the twenty-sixth annual meeting of the American Academy of Neurology, San Francisco, April 1974.
