[Angiography in the diagnosis of nasopharyngeal tumours (author's transl)].

The angiography of tumours of the nasopharynx is an important contribution to preoperative diagnostis. Applying modern, improved techniques (superselective catheterisation, magnification angiography, subtraction methods) it is possible to have an idea of the size and the localization of the tumour as well as of afferent and efferent vessels. Often a differential diagnosis is achieved; in some tumours (angiofibromas, haemangiomas, cysts, vascular malignant tumours) the angiographic findings are pathognomonic.
