6、肉瘤ERMSEmbryonalrhabdomyosarcoma胚胎型横纹肌肉瘤4贵阳医学院2012届硕士研究生论文前言随着影像医学技术的发展,计算机断层摄影(computertomography,CT)、磁共振成像(magneticresonanceimage,MRI)在临床上广泛应用,关于鼻腔息肉、肿瘤性病变的认识以及影像学在鼻腔鼻窦手术中的作用的研究已有较多文献报道,但系统综合研究各个疾病之间的鉴别诊断要点的相关文献报道较少。鼻腔占位包括鼻腔息肉和鼻腔肿瘤,临床诊断主要靠鼻腔镜检查,一般比较容易,但若合并感染或出血时,诊断有一定的困难,占位位于鼻腔深部或占位较大时,鼻腔
7、镜难以确定占位的范围、邻近组织结构以及骨骼受累及的情况和邻近鼻旁窦受累及情况,但CT能很好的显示这些。与平片和MRI比较,CT具有极佳的分辨骨、气体和软组织的能力。鼻窦CT与鼻腔镜紧密结合,是有效诊断鼻腔[1]占位性病变的方法。以往CT对鼻腔占位的诊断与鉴别诊断准确率不高,现回顾分析了我院2008-2012年经病理证实的鼻腔占位性病变138例,总结如下。1资料与方法1.1一般资料收集我院2008.01-2012.03经病理证实的鼻腔占位性病变138例,其中鼻腔水肿性息肉45例、出血坏死性息肉6例、内翻性乳头状瘤(n
