    Description / Table of Contents: Zusammenfassung Das Auftreten von Hirnmetastasen stellt für Patienten ein eingreifendes und oft lebensbedrohendes Ereignis dar. Eine adäquate Therapie erfordert besonnenes Handeln unter Abwägung aller Behandlungsoptionen. Multiple Hirnmetastasen sollten insbesondere bei schlechtem Allgemeinzustand einer palliativen Ganzhirnbestrahlung zugeführt werden. Bei Patienten mit einem günstigen Prognoseprofil, solitären oder wenigen Hirnmetastasen sind operative Exstirpation und Radiochirurgie gleichwertige Behandlungsmethoden, wobei die stereotaktische Einzeitbestrahlung nicht invasiv ist und auch in inoperablen Regionen durchgeführt werden kann. Der Stellenwert der zusätzlichen Ganzhirnbestrahlung ist noch umstritten. Die Überlebenswahrscheinlichkeit wird durch diese Kombination nicht verbessert, wohl aber kann die zusätzliche Ganzhirnbestrahlung das Auftreten neuer Hirnmetastasen verhindern.
    Notes: Summary Brain metastases are life-threatening events for patients. Adequate therapeutic strategies demand thoughtful planning and careful weighting of all treatment options. Multiple brain metastases should be treated in palliative therapy with whole-brain irradiation. In patients with a favourable prognosis and solitary or few brain metastases, surgical excision and radiosurgery are comparable adequate treatment options. Radiosurgery is an non-invasive procedure that can also be performed in non-operable brain areas. The value of additional whole-brain irradiation is under discussion. It has no influence on survival, but the frequence of new brain metastases may be reduced.

    Description / Table of Contents: Zusammenfassung. Arteriovenöse Fisteln der A. vertebralis sind eine bekannte Komplikation nach Direktpunktion der A. vertebralis zur Angiographie. Da diese Angiographietechnik verlassen wurde, tritt heutzutage die häufige Venenpunktion am Hals zum Einbringen zentralvenöser Katheter ätiologisch in den Vordergrund. Unsere Erfahrungen bei 4 Patienten sowie die Langzeitergebnisse nach gefäßchirurgischer Therapie werden geschildert.
    Notes: Summary. Direct puncture of the vertebral artery for angiography has been abandoned since the introduction of angiography catheters. Nowadays puncture of jugular veins for intravenous nutrition or monitoring is the predominant cause of accidental arteriovenous vertebral artery fistulas. We describe the history of four patients with such fistulas and the long-term results after surgical repair.

    Notes: Abstract We describe serial studies of focal cortical dysplasia causing temporal lobe seizures and progressive aphasia in a 54-year-old woman. Initially, MRI volumetry of the temporal lobes showed significant left cortical thickening corresponding to an elevated aminoacid uptake in the left temporoparietal and inferior frontal cortex on SPECT using 3-[123I]iodo-α-methyl-l-tyrosine (IMT). After 1 year there was severe shrinkage of the left temporal lobe, possibly the result of recurrent complex partial seizures.

    Notes: Summary Computed tomography (CT) has given us a new method for examining the orbit and its contents. The technique of examination is described, and the indications for the application of computed tomography in ophthalmology are considered: suspected orbital tumors, unilateral exophthalmos, pareses of the ocular muscles, traumatic lesions and malformations in the region of the orbit. The findings in 210 cases of orbital lesions examined in this study are reported and the differential diagnosis is discussed. Considerable improvement and greater accuracy in diagnosis have been achieved in the field of ophthalmology by using computed tomography. Early tumor visualization is possible without risk or discomfort to the patient.

    Notes: Summary Serial CT studies performed for 1 year on a female patient suffering from a pinealoma are reported. Under cobalt therapy (5000 rads) a remission of the pinealoma was achieved. A short time later, metastases developed and cobalt therapy was repeated (6000 rads). Rapid tumor remission was seen again, but rapid occurrence of probable metastases too. The question whether radionecrosis or metastases were present cannot be answered.

    Notes: Summary The CT patterns of 295 glioblastomas examined with pre- and postcontrast scans using an EMI scanner mark I (Matrix 160/160) have been reviewed and compared with the CT appearances of other brain tumors, metastases and abscesses. There is a great variety of CT patterns with glioblastomas. However, a garland-shaped CT appearance, representing a subgroup of ring-shaped lesions, seems to be most typical for glioblastomas since it was observed in 19% of ring-shaped glioblastomas but in only one out of 172 metastases and in no case of an astrocytoma grade II or an abscess in our series. The initial CT diagnosis, based on the CT finding, the patient's history and the clinical data, was correct in 69.8% of the glioblastomas, 41 recurrent glioblastomas included. In 12% of the cases the presence of a glioblastoma was within differential diagnosis. These results lead to the conclusion that in many cases additional diagnostic methods, such as serial scintigraphy and/or cerebral angiography, are required for a reliable differential diagnosis.

    Notes: Summary The paper deals with CT followup studies on 73 patients with cerebral tumors who received radiotherapy. The value of CT for the indication of radiotherapy, for followup therapy and for the demonstration of therapeutic success are discussed. Since the cerebral tumors become visualized by means of CT in their entire extent and can be differentiated from perifocal edema, the question arises whether radiotherapy should consist of higher doses in the future. It is also suggested that the “clinical malignancy” may be used to compare the behavior of cerebral tumors when there is no exact histological classification. The possible histopathological effects of radiotherapy (edema, necrosis) and their demonstration by CT are discussed.

    Notes: Abstract A 39-year-old healthy man had several transient ischaemic attacks suggesting left internal carotid artery (ICA) occlusion. There were no vascular risk factors and no preceding trauma. Colour-coded duplex sonography suggested a pseudo-occlusion of the left ICA, and cerebral angiography demonstrated dissection of the left ICA and both vertebral arteries. Angiography 6 months later was completely normal. This underlines the importance of four vessel angiography in young patients with dissections of cervical arteries.
