【摘要】目的:探讨鼻腔、副鼻窦内翻性乳头状瘤的CT平扫价值。方法:回顾我院2009年10月至今手术病理证实的鼻腔、副鼻窦内翻性乳头状瘤36例的CT平扫表现，其中男性28例，女性8例，年龄29~76岁，平均53岁。分析鼻腔、副鼻窦内翻性乳头状瘤的CT平扫价值。结果：36例均为单侧，呈形态不规则的软组织肿块影，多位于上颌窦口和筛窦交界处，常沿中鼻甲生长，常伴轻度鼻甲骨质吸收，并易引起同侧副鼻窦口梗阻而造成相应鼻窦积液、骨质增厚硬化。结论: CT平扫对鼻腔、副鼻窦内翻性乳头状瘤的检出具有很高的价值，对定性缺乏特异性，能提示鼻腔、鼻窦内翻性乳头状瘤的可能性，判断肿瘤的范围，为临床手术提供参考依据。

Methods:a retrospective review of our hospital from 2009 October up to now confirmed by operation and pathology of the nasal cavity, the paranasal sinus inverted papilloma in 36 cases of CT scanning performance, among which 28 cases were male, female 8, age 29~76 year old, average 53 years old. Analysis of the nasal, paranasal sinus inverted papilloma of the unenhanced CT value. Results:all the 36 cases were unilateral, a form of irregular soft tissue mass shadow, located in the ostium of maxillary sinus and ethmoid sinus junction, often along the middle turbinate growth, often accompanied by mild turbinate bone absorption, and easy to cause the ipsilateral paranasal sinus orifice obstruction caused by corresponding sinus effusion bone thickening, hardening. Conclusion: CT plain scanning in nasal cavity, the paranasal sinus inverted papilloma detection has the very high value of qualitative, lack of specificity, can prompt the nasal, paranasal sinus inverted papilloma possibilities, judge the extent of the tumor, to provide reference for clinical operation. ......
