Abstract
Radiographic findings previously thought pathognomonic for juvenile nasopharyngeal angiofibroma are anterior bowing of the posterior wall of the maxillary antrum on plain films or tomography, and a dense homogeneous blush on angiography. Two patients presented with nasopharyngeal masses which mimicked angiofibroma radiographically: 1 mass was a lymphoepithelioma and the other was a fibrous tumor. Constitutional symptoms and atypical physical findings should alert the physician to a diagnosis other than juvenile nasopharyngeal angiofibroma.
