    Notes: Summary Out of 155 cases of craniopharyngioma seen in the past 47 years, 19 are considered unusual. These 19 cases have been placed under the following headings— 1. unusual topography, and 2. associated vascular pathology. Since CT scanning offers important information about extension of craniopharyngiomas, it is very helpful for planning operative approach. However, cerebral angiography is still important for demonstrating vascular pathology.

    Notes: Summary In order to investigate the pathogenesis of periventricular lucency (PVL) in hydrocephalus, CT scans were performed with monitoring of the epidural pressure in a series of dogs with hydrocephalus induced with kaolin. PVL of various degrees was detected in the experimental animals, which disappeared immediately after a shunting operation. Correlations have been attempted between PVL on CT scans and histological examinations, contrast enhancement studies, metrizamide ventriculography, and measurement of regional cerebral blood flow in the periventricular white matter. PVL in hydrocephalus is considered to represent acute edema or chronic CSF retention in the periventricular white matter caused by an increase of water content. In other words, it is regarded as a sign of existing or preceding intraventricular hypertension on CT scan, and seems to be a reversible phenomenon to some extent. PVL may therefore became an indication for a shunt.

    Description / Table of Contents: Résumé Sept patients présentant un spondylolisthésis de degré III ou IV ont été traités par réduction du déplacement par traction, suivie d'arthrodèse corporéale par voie antérieure. Chez les deux sujets les plus jeunes (12 et 16 ans) une réduction parfaite a été obtenue par la seule traction halo-pelvienne. Cependant, les cinq autres cas ont nécessité une traction directe par fil (par voie postérieure) en plus de la traction halo-pelvienne ou fémorale. Le traitement terminé, tous les malades présentaient une fusion solide ainsi qu'une disparition complète de tous leurs symptômes.
    Notes: Summary Seven patients with severe lumbosacral spondylolisthesis were treated by reduction of the displacement followed by stabilisation by anterior interbody fusion. In the two youngest patients full reduction was achieved by halo-pelvic traction. In the remainder halo-pelvic or femoral traction was combined with a posterior wire reduction device. All patients achieved a sound fusion with complete remission of symptoms.
