Intravascular papillary endothelial hyperplasia (IPEH) is an unusual, benign, non-neoplastic, vascular lesion characterized histologically by papillary fronds lined by proliferating endothelium. Osteoma is a benign osteogenic lesion characterized by proliferation of compact or cancellous bone. Osteoma of the maxillary sinus is an uncommon lesion. The purpose of this report is to present a case with 2 different lesions (intravascular papillary endothelial hyperplasia and osteoma) occurring at the same time in 1 patient that may or may not be related to each other and to stress the value of diagnostic imaging.
血管内乳头状内皮增生（IPEH）是一种不常见的良性非肿瘤性血管病变，组织学特征为增生的内皮细胞排列成乳头状叶。骨瘤是一种良性成骨性病变，其特征为密质骨或松质骨增生。上颌窦骨瘤是一种罕见病变。本报告的目的是呈现1例患者同时出现2种不同病变（血管内乳头状内皮增生和骨瘤）的病例，这两种病变可能相关，也可能不相关，并强调诊断性影像学检查的价值。
