Harwood-Nash Department of Radiology Hospital for Sick Children Toronto Ontario Canada Summary The development of paediatric neuroradiology is a specific persuasion within neuroradiology and has increased in scope and significance throughout the last ten years. The emergence of computed tomography has altered the indications for types of neuroradiological procedures in infants and children. The sophistication, accuracy, and safety of standard neuroradiological procedures have been increased by the accuracy and safety of computed tomography, particularly in the premature infant. There is a growing need for education and instruction in paediatric neuroradiological techniques and paediatric neuroradiological diseases within the neuroradiological fraternity as a whole.

Chuang Margareta Resjo Department of Radiology Hospital for Sick Children Toronto Ontario Canada Summary Forty-three infants and children underwent conventional or CT ventriculography after instillation of metrizamide into the ventricular system. The procedure had few complications. Anatomic detail of intraventricular obstruction was good. With CT additional physiologic information can be obtained.

The authors review their experience with a series of 260 children with proven brain tumors. In most cases CT is so conclusive that other diagnostic techniques are no longer often needed. Pneumoencephalography in particular has largely been replaced by CT in recent years in the authors' departments, and the frequency of central ventriculography with contrast material has decreased substantially. Particular diagnostic difficulties with regard to tumors near to or within the caudal brain stem, some posterior fossa tumors, small vermian tumors, and tumors of the cerebral hemispheres are discussed.

Goldberg Department of Radiology Hospital of the University of Pennsylvania Philadelphia Pennsylvania USA Summary Computed tomography in 34 cases of meningitis has revealed a spectrum of findings. In acute cases these include enlargement of the subarachnoid spaces, generalized contrast enhancement of the meninges and ependyma, sterile and pyogenic subdural collections, cortical infarction, and cerebral necrosis.

Chuang Department of Radiology Hospital for Sick Children Toronto Ontario Canada Summary The air gap type of CT scanner with tilting gantry allows the use of head positions other than the standard semi-axial. The modified Water's or clival-perpendicular position is especially useful in the diagnosis of posterior fossa disease. The position offers a view that is approximately coronal to the clivus and tentorium. The clival-perpendicular view easily separates the supraand infratentorial compartments. It also helps to differentiate extra- and intra-axial lesions and to locate the fourth ventricle, and it gives far better vertical orientation of posterior fossa pathology.

Lee Division of Neuroradiology, Department of Diagnostic Radiology University of Rochester School of Medicine and Dentistry Rochester New York USA Summary Five cases, four histologically proven, of hamartoma of the tuber cinereum and hypothalamus in children are reported. The ages of the patients range from 2 to 12 years. Three cases had pubertas praecox, and in all of these the hamartoma was located in the basal cistern between the chiasm and pons and had a collar button shape and size typical of hamartoma of the tuber cinereum. In the third case, a huge calcified mass in the suprasellar region was initially thought to be craniopharyngioma. The fourth case had a hamartoma within the substance of the hypothalamus and presented with hyponatremia and temporal lobe seizures.

234 16 16 1 1 T. Reisner K. Zeiler P. Dal Bianco Neurologische Universitätsklinik Wien Wien Österreich Summary A total of 228 children suffering from seizure disorders were investigated by means of cranial computerized tomography (CT). Their age ranged from 3 weeks to 15 years. Structural abnormalities were assessed in 63% of these cases. The greatest incidence of organic abnormalities occurred in children with major epilepsy (83%) and with focal seizures (71%). Clinical data and the course of illness may require additional angiographic and repeated CT investigations.

Stovring Departments of Neurology, Radiology and Pediatrics University of New Mexico Medical Center Albuquerque New Mexico USA Summary CT in childhood bacterial meningitis has indicated that bacterial meningitis is more than an inflammation of the subarachnoid space; it is a disease process which often exerts a profound effect on the brain parenchyma. In some cases ventricular widening may be a reflection of loss of brain substance rather than increased intracranial pressure. A vasculitis may occur in cerebral vessels with consequent ischemic infarct. The abnormalities found on CT during the acute illness are frequently persistent.
