title: [Tomodensitometry of the orbit. Possibilities of an approach to histopathological diagnosis (author's transl)].
abstract: The value of scanning lies above all in the determination of the site, size and shape of orbital lesions and, where applicable, their relations with neighbouring extra or intra cerebral structures. But certain conditions such as exophthalmos during hyperthyroïdosis have characteristic scan findings. Even intra-ocular tumors are visible on elarged scanfilms. It nevertheless remains difficult to attempt to predict a histological diagnosis on the only basis of scan findings. Particular emphasis must be placed upon the contribution of techniques of treatment of the films obtained (enlargement, contrast media, histograms, lateral views) as well as the complementary use of phlebography and ultrasonography.
