    Notes: Summary By means of a case report a shortcoming of balloon catheter techniques for intravascular occlusion of CCF is demonstrated: the procedure by which the balloon is detached from the filling catheter is unreliable and may further traumatise the vessel wall. We describe a new technique that allows careful, gentle, and effortless detachment of the balloon by means of a melting-off technic.

    Notes: Summary Medulloblastoma and acute lymphocytic leukemia patients treated by intrathecal methotrexate and radiation were investigated by means of computerized axial tomography. More than 50% of them turned out to have acquired encephalopathy. Only gross morphologic brain defects, as visualized by computerized tomography, caused manifest clinical signs of brain dysfunction, such as epilepsy, mental retardation, paresis, and apallic syndrome. Mild morphologic changes were found even in asymptomatic children. The preferred site of defects in brain substance was the paraventricular white matter.

    Notes: Summary Twenty-three patients complying with the clinical criteria for brain death were studied by contrast-enhanced CT. In all but one, the great intracranial vessels escaped visualization; accordingly, angiography demonstrated cerebral circulatory arrest. In the remaining case, faint enhancement of the circle of Willis corresponded to angiographic demonstration of the proximal segments of cerebral arteries. Neither in normal brain nor in dead brain did slow CT scanning disclose any postcontrast increase in parenchymal attenuation. An improved technique is proposed to demonstrate the transit of the contrast bolus by rapid CT with image splitting. If cerebral blood flow is preserved, the grey and white matter will enhance significantly following administration of contrast medium. Vice versa, the absence of enhancement confirms brain death, even in instances in which the great cerebral vessels are obscured by hemorrhage or other extensive lesions. Two additional cases of brain death were evaluated by rapid CT scanning. As to brain death, the technique obviates the need for angiography or radionuclide angiography, usually applied in prospective organ donors, because its informative content is superior to that of either method. The CT technique described affords a reliable and safe diagnosis of brain death, and can be interpreted easily.

    Description / Table of Contents: Résumé La ventriculographie positive au Dimer X a permis de constater un recessus infundibulaire intrahypophysaire chez une femme de 34 ans atteinte d'hydrocéphalie obstructive. Les auteurs admettent la pathogénie malformative.
    Abstract: Zusammenfassung Bei einer 34-jährigen Patientin mit Hydrocephalus bei Liquorpassagestörung durch einen Mittelhirnprozeß kam im Ventrikulogramm mit Dimer X ein abnormer intrasellarer Recessus des 3. Ventrikels zur Darstellung. Nach seiner Lokalisation und nach ontogenetischen sowie phylogenetischen Gesichtspunkten ist er als persistierender intrahypophysärer Recessus infundibuli zu bezeichnen. Eine Fehlbildung infolge einer Entwicklungshemmung wird angenommen.
    Notes: Summary X-ray examination of the intracranial ventricles with Dimer X made it possible to make the diagnosis of obstructive hydrocephalus due to a mass lesion of the midbrain and an abnormal intrasellar recess of the third ventricle in a 34 year old female patient. Considering the location and ontogenetic and phylogenetic facts one can diagnose the second pathological finding as a persisting intrapituitary recessus infundibuli. A malformation due to inhibition during development is to be assumed.

    Notes: Summary “Ethibloc” has been used almost exclusively until now for embolization of tumors and bleeding vessels in the liver and kidney. Unlike with Gelfoam-particles, there is no recanalization. The resorption occurs so slowly that there is no interference with the necrosis of the embolized tumor. Due to its low viscosity, it passes catheters with thin lumina and fills the capillary bed of the tumor without danger of reaching the venous vessels. In this paper we describe a new technic of percutaneous catheter-embolization with Ethibloc using a coaxial catheter which we believe enhances safety and effectiveness. It has been successfully used in five patients. In the meantime two more patients have been treated successfully.

    Notes: Summary Fissures in the anterior arch of the atlas are rare. The defect can properly be diagnosed on axial radiographs and can be suspected in studying carefully the lateral x-ray. The developmental cause of the split anterior arch and its clinical significance are discussed. A median cleft, analogous to a fissure in the anterior arch of the atlas, may also occur in the proatlas, as schown in one case.

    Description / Table of Contents: Zusammenfassung 50 chronische Alkoholiker (37 Manner und 13 Frauen im Alter von 26 bis 56 Jahren, Durchschnittsalter 39,9 Jahre) mit unterschiedlichen klinischen Syndromen (Alkoholpsychosen, metalkoholische Encephalopathien) wurden computertomographisch untersucht. In 96% (in 80% höhergradig) war eine cerebrale Atrophie nachweisbar. Fast immer handelte es sich um zugleich corticale und subcorticale Veränderungen, wobei gegenüber der Pneumencephalographie die zuverlässige Darstellung gerade auch corticaler Atrophien hervorzuheben ist. Einschränkend muß jedoch betont werden, daß man anhand der CT nicht sicher sein kann, daß eine Erweiterung der äußeren Liquorräume durch eine Degeneration der grauen oder der benachbarten Ausläufer der weißen Substanz hervorgerufen wird (Windungsatrophien). Die computertomographischen Befunde wurden auf ihre Beziehungen zu Lebensalter, Geschlecht, Abususdauer und -schwere, klinischem Syndrom, Rezidivhäufigkeit (und auch Anfällen) u.a.m. untersucht. Dabei zeigte sich in erster Linie ein Zusammenhang mit der Abususdauer und dem Lebensalter, weniger deutlich mit der Abususschwere. Die ausgeprägtesten Veränderungen fanden sich beim deliranten Syndrom und Psychose-Rezidiven, vor allem in Verbindung mit hirnorganischen Anfällen. Die stärksten Erweiterungen des 3. Ventrikels wiesen Wernicke-Korsakow-Encephalopathien mit in der Vorgeschichte wiederholten Entzugssyndromen auf. Die an 10 Patienten jeweils während der floriden Psychose und vier Wochen danach vorgenommenen computertomographischen Untersuchungen ergaben identische Befunde; passagere Veränderungen (z.B. ein Hirnödem) ließen sich also nicht fassen. Die craniale Computertomographie erscheint vorzüglich dazu geeignet, den vielen noch offenen Fragen wie z.B. dem Alter, der Abususdauer und-schwere in ihrer speziellen pathogenetischen Wertigkeit für die im Rahmen des Alkoholismus auftretenden cerebralen Atrophien insbesondere an größeren Kollektiven weiter nachzugehen.
    Notes: Summary Fifty chronic alcoholics (37 men and 13 women, ages 26–55, mean age 39.9 years) with different clinical syndromes (alcoholic psychosis, alcoholic encephalopathies) were studied by computerized cranial tomography. Cerebral atrophy was detected in 96% of all cases. Combined cortical and subcortical signs were encountered in almost all cases. Cortical atrophy seemed to be detectable more easily by CT than by pneumencephalography. The computerized tomographic findings were studied in their relations to age, sex, duration of abuse, clinical syndromes, frequency of relapse (and seizures, too), etc. Cerebral atrophy was correlated primarily with the subjects' age and the duration, and less with the intensity of alcoholism. The most distinct changes were found in delirium syndromes and, in cases with relapse of psychosis, especially in combination with seizures. Wernicke-Korsakow encephalopathies showed the widest third ventricles when combined with repeated syndromes of withdrawal in their case histories. Computerized tomographic examinations of ten patients during acute psychosis as well as 4 weeks later showed identical findings; transitory changes, e.g., cerebral edema, were not detected. Computerized cranial tomography appears to be extremely useful to study the numerous open questions concerning the pathogenetic role of age, duration, and severity of abuse with cerebral atrophy.
