[Topographical diagnosis of orbital lesions with contact B-scan ultrasonography (author's transl)].
With contact B-scan ultrasongraphy it is possible, to determine the topographical relations of space occupieing lesions to the main orbital structures. This enables the examiner to answer three important questions: (1) In which part of the orbit the lesion is located? (2) Is the proptosis produced by a lesion separate from the muscles and the optic nerve or (3) are these structures themselves affected? Our results are compared with those made by A-scan ultrasonography. The existing range of echographical patterns known of orbital tumors is thus widened by the topographical diagnosis elicited by contact B-scan ultrasonography.
