    Notes: Summary The authors describe a new instrumentation for repositioning of the Brown-Roberts-Wells (BRW) stereotaxic system, useful for precise fractionated radiotherapy. A lucite ring is fixed to the patient's skull with four screws. Another ring, partially open, is then firmly connected co-axially to the lower part of the first one with four spacer-bars. The fixture permits an exact repositioning of the B.R.W. stereotaxic system, placing the target point in the linear accelerator isocenter. The preliminary technical results obtained in five children are reported and the fixture performance, advantages, and perspectives are discussed.

    Notes: Summary The authors describe a new method for reproducible, non-invasive fixation of a stereotaxic localizing frame. A localizing system similar to that of Brown-Roberts-Wells for MR can be fixed at the base of the facial skeleton to the upper dental arch by an orthodontic resin plate. Results of trials with CT scan, advantages and disadvantages are discussed. The new fixture could be employed in open surgery and in fractionated radiotherapy.

    Description / Table of Contents: Résumé L'étude des tumeurs de la fosse postérieure à l'aide d'un produit de contraste hydrosoluble introduit directement dans le 3ème ventricule visualise de fines structures anatomiques plus nettement que d'autres méthodes, ce qui est important pour l'obtention d'un diagnostic topographique précis en cas de processus expansif, condition essentielle pour un traitement correct. Les auteurs décrivent le mode d'exécution et les critères du diagnostic différentiel des diverses localisations.
    Abstract: Zusammenfassung Es wird über die Untersuchungen mit wasserlöslichen Kontrastmitteln bei Tumoren der hinteren Schädelgrube berichtet. Dabei wird das Kontrastmittel direkt in den 3. Ventrikel injiziert. Bei dieser Untersuchungsmethode sind die anatomischen Strukturen besser erkennbar als bei anderen Untersuchungen. Die Detail-Diagnostik ist besonders wertvoll für eine genaue topographische Diagnose der intracraniellen Raumforderungen. Die Untersuchungstechnik und die differentialdiagnostischen Kriterien für die unterschiedlichen Lokalisationen werden beschrieben.
    Notes: Summary The study of posterior fossa tumors with a watersoluble contrast medium introduced directly into the third ventricle demonstrates some anatomical structures more clearly than with other materials. This detail is useful for a precise topographical diagnosis of space-occupying lesions. The mode of execution and the differential diagnostic criteria for the various localizations are described from a study of 107 cases.

    Description / Table of Contents: Résumé La présence d'un spasme artériel cérébral introduit un pronostic défavorable. Le mauvais pronostic peut être amélioré par le choix judicieux du moment de l'intervention chirurgicale, lorsque le spasme a diminué, et en appliquant la corticothérapie intrarachidienne. Le pronostic varie également en fonction de l'âge du malade, de la topographie de l'anévrisme et de la disposition du cercle de Willis.
    Abstract: Zusammenfassung Der Nachweis von cerebralen Gefäßspasmen ist ein ungünstiges prognostisches Zeichen, wie die Autoren an ihrem eigenen Krankengut nachweisen konnten.
    Notes: Summary The presence of a cerebral arterial spasm carries an unfavourable prognostic significance. The poor prognosis can be improved by wisely choosing themoment of operation, to be performed once the spasm has subsided, and by applying intrathecal corticoid therapy. It appears also modified in relation to various factors, such as age of the patient, topography of the aneurysm and pattern of Willis's circle.

    Notes: Summary We present a retrospective study of occult spinal dysraphism in 47 children aged 0 to 14 years, all studied with plain X-rays, 60% with CT and myelo-CT, and 40% with MR. We consider the classification and grading of these malformations, clinical, neuroradiological patterns, and indications for surgery. In the light of our findings and of the published data MR emerges as the key investigation. Only in a few cases of great anatomical complexity is it now necessary to perform CT and myelo-CT as well. A case in point is when the conus and thickened filum terminale are inextricably bound together and can no longer be considered separate structures. We propose the term “neurofibrous structure” to define the conus-thickened-filum-terminale unit when these structure are no longer distinguishable.
