Juvenile angiofibromas (JAF) and angiomatous polyps (AP) are vascular histologically benign tumors presenting with an identical clinical triad. Both lesions can be differentiated by their typical geographic pattern of growth, different pattern of tumor extension and their highly characteristic angiographic and angiocomputertomographic appearance. Time-density curves were of no use in differentiating the big variety of hypervascular lesions from each other. CT images of the vascular tumor phase after bolus injection of contrast medium however showed interesting pathomorphological details, which were extremely useful in differentiating JAF from AP and other vascular tumors. It is our opinion, that invasive angiography for diagnosing JAF has been surpassed, but is further essential for mapping of tumor perfusion, feeding vessels and praeoperative embolization therapy.
青少年血管纤维瘤（JAF）和血管性息肉（AP）是组织学上的血管良性肿瘤，具有相同的临床三联征。这两种病变可通过其典型的生长区域模式、不同的肿瘤扩展模式以及高度特征性的血管造影和血管计算机断层扫描表现来区分。时间-密度曲线在区分多种高血运病变方面并无用处。然而，在静脉注射造影剂后的血管肿瘤期CT图像显示出有趣的病理形态学细节，这对区分JAF与AP及其他血管肿瘤极为有用。我们认为，用于诊断JAF的侵入性血管造影已被超越，但对于肿瘤灌注、供血血管的定位及术前栓塞治疗仍至关重要。
