摘要
目的探讨鼻窦增强核磁共振(MRI)在鼻内翻性乳头状瘤(NIP)诊断中的应用价值。方法对该院2014年1月—2014年11月收治的经病理确诊并行手术治疗的55例NIP患者手术前的增强MRI中瘤体表现特点进行回顾性分析,对增强MRI对于NIP的诊断价值进行分析。结果 NIP的增强MRI表现:瘤体表面分叶状22例(40%);信号强度:多数为等-长T1、稍长-长T2信号影。经增强扫描后发现瘤体出现不均匀或均匀强化。条纹样改变:其中25例(45.45%)患者存在高低信号相间条纹状变化;阻塞性炎症18例(32.73%);7例(12.73%)患者病变为:以肿瘤的附着点为中心向周围呈放射状生长。增强MRI的NIP分期符合率显著高于CT扫描,差异有统计学意义(P<0.05)。结论鼻窦增强MRI扫描能够对NIP瘤体及阻塞性炎症进行较好区分,对于NIP的临床分期诊断具有重要价值。
Objective To analyze the application value of sinus enhance magnetic Resonance Imaging （MRI） in nasal inverted papilloma （NIP） diagnosis. Methods Select 55 cases with NIP who were pathological diagnosis and treated by surgery as objective, retrospectively analyze the enhance MRI imaging features of NIP, and study the diagnosis value of enhance MRI in NIP. Results The enhance MRI features of NIP are：22 cases（40%）with lobulated tumor surface;signal strength：most are same length T1, long-short T2 image signals. Tumor has even and uneven enhance. Pattern changing： 25 cases （45.45%） has belted outcrop pattern changing; 18 cases（32.73%） has inflammation obliterative;7 cases （12.73%） are： select tumor attachment point as center and grow to the round radially. The coincidence rate of enhance MRI is much higher than that of CT （P〈0.05）, the difference has statistical significance. Conclusion Sinus enhance MRI can distinguish the NIP tumor and inflammation obliterative, has importance value in NIP clinical staging diagnosis.
