目的：探讨ＣＴ对内翻性乳头状瘤的诊断价值。方法：对１５例病理诊断为内翻性乳头状瘤患者鼻腔、副鼻窦轴位和冠状位ＣＴ资料进行回顾性分析。结果：本组１５例患者均表现为鼻腔及鼻窦内软组织肿块影，并累及邻近组织，部分造成骨质破坏。结论：ＣＴ对内翻性乳头状瘤的定性诊断存在一定限度，但对病变的大小、范围及手术方案的制定和预后估计有重要作用
Objective: To investigate the value of CT in the diagnosis of inverted papilloma. Methods: The CT data of nasal cavity, paranasal sinuses and coronal CT were retrospectively analyzed in 15 cases of pathological diagnosis of inverted papilloma. Results: All the 15 patients presented with soft tissue mass in the nasal cavity and paranasal sinuses, involving adjacent tissues and partly causing bone destruction. Conclusion: There is a certain limit to the qualitative diagnosis of inverted papilloma with CT, but it plays an important role in the size and scope of the lesion and the formulation and prognosis of the surgical plan
