    Description / Table of Contents: Zusammenfassung Zwischen 1969 und 1979 wurden in der neurochirurgischen Universitätsklinik Essen 79 Patienten an einer Liquorfistel operiert. Eine veränderte Einteilung, der Beginn der Symptome und die diagnostischen Untersuchungsmethoden werden besprochen und die Resultate anhand der Literatur miteinander verglichen. Ebenfalls wird ein Patient mit einer orbitalen Liquorrhore vorgestellt.
    Notes: Summary Between 1969 and 1979, seventy-nine patients suffering from a cerebrospinal fluid (CSF) leakage, were operated on in the neurosurgical department of the University Clinic Essen (West Germany). A modified classification, the onset of symptoms and the diagnostic procedures are described and some data are compared with the results of other investigators. Other methods of closing a CSF fistula and the timing of operation are briefly discussed. Also the case history of a patient with orbitorrhoea is described.

    Description / Table of Contents: Zusammenfassung Anhand von drei klinisch und histologisch gesicherten Fällen von sogenanntem traumatischen cerebralen Aneurysma (A.basilaris, A. communicans posterior, A. lenticulostriata)wird aufgezeigt, daß es sich bei den akuten und subakuten Fällen in der Regel nicht um wahre Aneurysmen im Sinne der pathologisch-anatomischen Definition, sondern um traumatische akute Schlagaderschädigungen mit periarteriellem Hämatom (Aneurysma spurium) und somit um Pseudoaneurysmen handelt. Differential-diagnostisch ist ein derartiges Pseudoaneurysma nicht allein radiologisch oder klinisch vom kongenitalen Aneurysma zu, unterscheiden. Hierzu bedarf es einer histologischen Diagnose. Eine durch stumpfe Gewalteinwirkung indirekt entstandene intracranielle Arterienruptur mit Bildung eines Pseudoaneurysma ist auch ohne Schädelbasisfraktur möglich. Da traumatische Schädigungen der Striatumarterien insbesondere bei Kindern und Jugendlichen möglich sind, spricht die Lokalisation der Blutung in den Stammhirnkernen nicht gegen die traumatische Ätiologie. Für die Latenzzeit zwischen Trauma und Ruptur eines sogenannten traumatischen Aneurysma bzw. Pseudoaneurysma sind reparative Vorgänge in der Schlagaderwand und deren Umgebung von Bedeutung.
    Notes: Summary Three clinically and histologically verified cases of “traumatic aneurysm” concerning the a.basilaris, a. communicans posterior, and a. lenticulostriata have been used to demonstrate that these acute and subacute lesions do not belong to the true aneurysms, as defined pathologically and anatomically. They can be considered as acute traumatic lesions of arteries with periarterial hematoma (aneurysma spurium) and should be designated as pseudoaneurysms. Such pseudoaneurysms must not only be differentiated from true aneurysms by radiological and clinical findings but also by histological investigation. An intracranial artery rupture with formation of an pseudoaneurysm due to a blunt injury can also exist without a fracture of the base of the skull. Since traumatic lesions of the striatum arteries are caused especially in children and young adults, the localization of an acute hemorrhage in the basal ganglia does not exclude a traumatic etiology. Early closure of the injury in the artery wall and surroundings by fibrin and thrombotic material with following repairing processes are important for latency between injury and rupture of the pseudoaneurysm.

    Notes: Summary Thirty-six patients undergoing Dimer X or Amipaque ventriculography or myelography underwent electroencephalographic investigations. In most cases EEG alterations were found. They ranged from general slowing to seizure potentials. These findings and their causes are discussed.

    Notes: Summary A CT/T 8800 (General Electric) CT scanner was used to study lumbar disc disease in fifty patients. In seven patients so-called computed tomography mexrizamide myelography was performed, whereas in the remaining cases no contrast enhancement was used. Multiplanar reconstructions were done. Irradiation exposure was measured during the investigations and compared with data during conventional myelography. We found that lumbar CT scanning is not a screening method in cases of lumbar disease, but the aimed use gives further information about the underlying process and its differential diagnosis. Multidirectional reconstructions reduce the number of diagnostic errors. This procedure does not increase the radiation exposure dose in comparison with conventional myelography.
