[A new topographic method for localising the venous angle of the deep cerebral veins on the lateral phlebographic phase (author's transl)].

A simple topographic method has been developed for the localisation of the venous angle on the lateral cerebral phlebogram. The principle depends on an angular measurement and an estimation of proportions which are statistically independant of each other. The method was tested on 103 phlebograms of adult patients with supratentorial spaceoccupying lesions. It was compared with conventional measurements; a number of advantages were found for using our method and its accuracy is as good as the other, most precise, methods.

[Von Recklinghausen's neurofibromatosis with intracranial stenosis of the internal carotid artery and orbito-sphenoidal bone dysplasia (author's transl)].

A patient with fibromatosis of the skull and a so-called "parophthalmicus syndrome" is described in whom there was hypoplasia and stenosis of the homolateral internal carotid artery and aplasia of the ophthalmic artery. The vascular changes in this phakomatosis are discussed. We suggest that the vascular changes in the carotid be included in the extended parophthalmicus syndrome.

A new topometric method of determining the position of the venous angle on cerebral phlebograms.

The authors devised their own craniometric method of determining the normal position of the venous angle on the lateral phlebogram. The fundamental principles of the method are as follows: (1) two auxiliary lines; i.e. (a) a horizontal line the nasion - the tuberculum sellae (N-TS); (b)a diagonal line the nasion - the tabula interna (N-Ti); (2) the two auxiliary lines form the angle alpha, which is equal to 20.44+/- 4.2 degree; (3) the proportional position of the venous angle (the point of intersection S on the diagonal N-Ti) is the ratio of the distance N-S to the total length of the diagonal N-Ti,i.e.: (formula: see text). The value is equal to 49.8 +/- 4.6%. The present method takes into consideration both the length and the height of the skull, has a small statistical dispersion and is simpler than the other available methods.
