Juvenile nasopharyngeal angiofibroma: radiographic aspects.
Because of consistent and unique radiographic features of JNA, it is not necessary, nor is it advisable, to biopsy these tumors to establish a diagnosis. In addition, the carotid arteriograms show the major feeding vessels to the lesion and also completely delineate the periphery of the tumor, thus establishing operability versus non-operability. If a JNA is treated by radiotherapy, the changes effected can be followed by carotid arteriography.
