Intravascular papillary endothelial hyperplasia (IPEH) is usually a cutaneous lesion thought to represent a peculiar manifestation of an organizing thrombus. The principal significance of IPEH is its microscopic resemblance to angiosarcoma and possible misinterpretation as such. The occurrence of IPEH in the paranasal sinus is exceedingly rare. In this article, we report the first case to our knowledge of IPEH in a vascular lesion that originated from the ethmoid sinus and extended into the sphenoid sinus and sella. Despite the benign nature of this lesion, it could have been mistaken for a malignant tumor because of its clinical course and radiologic findings.
血管内乳头状内皮增生（IPEH）通常是一种皮肤病变，被认为是机化血栓的一种特殊表现。IPEH的主要意义在于其在显微镜下与血管肉瘤相似，可能会被误诊为此类疾病。IPEH发生于鼻窦极为罕见。在本文中，我们报告了首例据我们所知起源于筛窦并延伸至蝶窦和鞍区的血管病变中的IPEH。尽管该病变性质为良性，但因其临床病程和影像学表现，可能被误诊为恶性肿瘤。
