【摘要】： 目的总结鼻腔及鼻窦内翻性乳头状瘤(NIP)的CT和(或)MR／表现的特点；评价鼻腔及鼻窦CT和(或)MRI检查在NIP临床分期中的作用；探讨NIP的原发部位在CT和(或)MRI表现的特点。方法回顾性分析经手术及病理证实的42例NIP的CT和(或)MR／及手术资料。结果本组病例CT和(或)MR／扫描均表现为鼻腔及鼻窦内软组织肿块影,并累及邻近组织,引起良性的骨质受压、吸收破坏和增生硬化等改变,病灶密度不均,轻至中度增强。按照Krouse[1]分级标准,将本组病例分为四级(四组)。在每组中将CT和(或)MR／分期与手术所见分期比较,结果如下(相符／不相符)：T1期2／1,T2期7／4,T3期20／2,T4期6／0,总共35／7。手术中可见原发部位共21例,其余病例由于肿瘤较大,难以判断病灶原发部位。21例中根据CT和(或)MRI有9例可见原发部位。结论 CT和(或)MRI对NIP无特异表现,对NIP定性诊断存在一定限度。CT可清晰显示骨质破坏情况,MRI能更清晰准确显示病变侵犯范围,两者结合能够为NIP的诊断及治疗提供更全面准确的信息。根据CT和(或)MRI可为NIP术前进行较准确分级,为治疗方案的选择提供重要信息。在疾病发生早期,病变范围较局限时可见原发部位。
[Abstract]:Purpose To summarize the CT and / or Mr / or MRI features of nasal cavity and sinusoidal inverted papilloma, to evaluate the role of CT and / or MRI in the clinical staging of NIP, and to explore the features of the primary location of NIP in CT and / or MRI. Method Ct and MRI findings of 42 cases of NIP proved by operation and pathology were analyzed retrospectively. Result Ct and / or Mr / scan showed soft tissue masses in nasal cavity and paranasal sinuses, and involved adjacent tissues, resulting in benign bone compression, absorption destruction and hyperplasia and sclerosis. The density of the lesions was uneven and mild to moderate enhancement. According to Krouse [1] classification standard, the patients were divided into four groups (4 groups). In each group, CT and / or MRT / staging were compared with surgical staging, and the results were as follows: (consistent / discordant): t 1 2 / 2 1 T 2 7 / 4 T 3 20 / 2 T 4 6 / 0, total 35 / 7. The primary site was found in 21 cases during the operation. In the remaining cases, it was difficult to judge the primary location of the lesion because of the large tumor. Among the 21 cases, 9 cases showed the primary site according to CT and / or MRI. Conclusion Ct and / or MRI have no specific manifestations for NIP, and there are certain limits in qualitative diagnosis of NIP. Ct can clearly show the bony destruction. MRI can more clearly and accurately show the extent of lesion invasion. The combination of the two can provide more comprehensive and accurate information for the diagnosis and treatment of NIP. According to CT and / or MRI, NIP can be classified accurately before operation, and it can provide important information for the choice of treatment plan. At the early stage of disease, the primary site can be seen when the lesion is limited.
