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: one 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.
以前认为对青少年鼻咽血管纤维瘤具有诊断意义的影像学表现为，在平片或体层摄影中上颌窦后壁向前弯曲，以及血管造影时出现浓密均匀的造影剂充盈。两名患者表现为鼻咽部肿块，影像学上类似血管纤维瘤：一个肿块是淋巴上皮瘤，另一个是纤维瘤。全身症状和不典型的体格检查结果应提醒医生考虑青少年鼻咽血管纤维瘤以外的诊断。
