    Description / Table of Contents: Résumé L'auteur a étudié les signes angiographiques dans 13 cas d'acromégalie due à une tumeur hypophysaire et les a comparés à 100 cas normaux. Dans 8 cas, il a pu observer des branches intra-caverneuses dilatées alimentant la tumeur. Dans les cas de tumeur asymétrique les branches caverneuses de l'artère carotide étaient plus importantes du côté où la tumeur était plus volumineuse. Des branches caverneuses hypertrophiques de l'artère carotide interne avaient été rapportées préalablement dans des cas d'adénomes chromophobes mais non dans des cas d'adénomes éosinophiles.
    Abstract: Zusammenfassung Es werden die angiographischen Befunde bei 13 Patienten mit einer Akromegalie (hervorgerufen durch einen Hypophysentumor) geschildert. Dabei konnte eine Erweiterung der Sinus cavernosus-Arterien beobachtet werden, die auf der Seite des größeren Tumorwachstums ausgeprägter waren. Bisher wurden bei eosinophilen Adenomen hypertrophierte Cavernosusäste der A. carotis interna nicht beschrieben.
    Notes: Summary The angiographic findings in 13 cases of acromegaly due to pituitary tumour have been studied and compared with those of 100 “normal” cases. Dilated cavernous sinus branches feeding the tumour were seen in 8 cases. In tumours with asymmetrical growth the cavernous branches of the carotid artery were more prominent on the side where the tumour was largest. Hypertrophied cavernous branches of the internal carotid artery have been reported previously in chromophobe but not in eosinophilic adenomas.

    Early contrast enhancement of acoustic neuroma (1978)
    Springer
    Neuroradiology 17 (1978), S. 31-33

    ISSN: 1432-1920
    Keywords: Computed tomography ; Contrast medium enhancement ; Acoustic neuroma

    Topics: Medicine
    Notes: Summary The changes of the enhancement of the lesion with time after intravenous administration of contrast medium were measured with computed tomography (CT) in 23 cases of acoustic neuroma. The pattern of high initial enhancement followed by a fairly rapid decrease is confirmed. A more rigorous study of the enhancement pattern using a mathematical description of the enhancement curve of the tumor as well as a measurement of the individual blood enhancement curve is discussed.

    Attenuation values of the cerebrospinal fluid (CSF) (1978)
    Springer
    Neuroradiology 15 (1978), S. 165-166 
    Details
    ISSN: 1432-1920
    Keywords: Computed tomography ; Cerebrospinal fluid ; Attenuation value
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The attenuation value of CSF, obtained by lumbar puncture, was determined with computed tomography in 25 patients. Measurement of the protein content in the same samples showed no correlation with the attenuation value. It is concluded that in the normal range of protein concentrations, the effect on the attenuation is insignificant and that the attenuation value of the CSF might be used to check large deviations in the CT numbers due to artifacts.

    Evaluation of the internal auditory meatus with acoustic neuromas using computed tomography (1979)

    Keywords: Computed tomography ; Internal auditory meatus ; Skull ; Acoustic neuroma ; Diagnosis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Forty-seven patients with 48 unoperated acoustic neuromas have been studied by computed tomography (CT) with respect to bone changes. CT and conventional X-ray examination of the skull were compared. The importance of using a small collimator, proper selection of the plane of the CT section and changing of the window level is stressed. CT detects porus changes as accurately as conventional X-ray methods.

    Notes: Summary Suspected lesions in and around the sella were examined by CT in 129 cases. The diagnostic accuracy and various technical aspects of the method are described. The mean attenuation and enhancement after administration of contrast material are evaluated in craniopharyngiomas, chromophobe adenomas, meningiomas, aneurysms, dermoid cysts, an arachnoid cyst and a glioma. The choice of collimator and its use in relation to sellar dimensions, particularly the sellar depths, are emphasized.

    Attenuation changes of the ventricular CSF after intravenous injection of contrast material (1978)

    Notes: Summary The CT attenuation change of the intraventricular CSF after i. v. administration of contrast material has been studied in 20 patients. A very small increase of attenuation was observed in the entire material. The method does not seem to be appropriate at present for the study of small attenuation changes in the CSF reflecting the passage of contrast material.

    Notes: Summary Seven pontine angle meningiomas were examined with computed tomography (CT). The result was compared with that of a study of 61 acoustic neuromas. These two tumor types differ in manner of growth, volume, shape,attenuation, attachment to bone, cisternal deformation, frequency of calcification, peripheral edema, and bone changes.

    Attenuation profiles of the petrous bone with acoustic neuroma (1980)
    Springer
    Neuroradiology 19 (1980), S. 123-129 
    Details
    ISSN: 1432-1920
    Keywords: Computed tomography ; Acoustic neuroma ; Internal auditory meatus ; Attenuation profiles
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Attenuation profiles across the petrous bone covering the whole internal auditory meatus (IAM) were constructed from the printouts obtained by computed tomography (CT) with narrow collimation performed on 12 patients with 13 acoustic neuromas. In healthy patients the attenuation profiles of right and left petrous bone were very similar in shape. The attenuation values of the individual pixels in the pixel columns of the printout located at the site of the porus and the IAM reflected the demineralization of the petrous bone and the widening of the porus and the IAM caused by the acoustic neuroma. A widening deep in the meatus was demonstrated in a patient with an intracanalicular tumor, and therefore it seems possible to make this diagnosis by CT scanning combined with the construction of attenuation profiles across the petrous bone. In the presence of unilateral acoustic neuroma there was a significant and characteristic difference in shape between the attenuation profiles of the two sides with generally lower attenuation values on the tumor side together with signs of widening of the porus and the IAM. In cases of bilateral acoustic neuroma comparison of the attenuation profiles can be made with mean attenuation curves obtained from scanning normal petrous bones. The prevailing physical limitations for demonstrating a narrow bony canal like the IAM with CT was experimentally analyzed using bone-simulating plastic material.
