Meningiomas originating in the paranasal sinuses are rare. These tumors are thought to arise from embryonal arachnoid nests which were pinched off and left behind during embryonic development. We have described various radiographic findings of two patients with meningioma arising in the paranasal sinuses (frontal sinus origin in a 65-year-old female, and sphenoid sinus origin in a 26-year-old female). The paranasal origin of meningioma was accurately determined on the basis of CT and arteriography. A review of the 11 cases previously reported and our cases indicates that there are no specific clinical or radiographic findings of meningiomas of the paranasal sinuses.
起源于鼻窦的脑膜瘤很罕见。这些肿瘤被认为起源于胚胎期蛛网膜巢，它们在胚胎发育过程中被挤压并遗留下来。我们描述了两名鼻窦脑膜瘤患者的各种影像学表现（一名65岁女性起源于额窦，一名26岁女性起源于蝶窦）。基于CT和动脉造影准确确定了脑膜瘤的鼻窦起源。对先前报道的11例病例及我们的病例进行回顾表明，鼻窦脑膜瘤没有特定的临床或影像学表现。
