36例鼻窦肉瘤患者CT和MRI表现

目的：探讨鼻窦肉瘤的CT和MRI影像学表现,提高其诊断的准确性。方法回顾性分析我院2008年1月~2014年1月经病理学证实的36例鼻窦肉瘤患者的CT和MRI的影像学资料,探讨影像诊断价值。结果肉瘤典型的MRI表现为稍长T1稍长T2信号,增强后中度强化。30例病变中心位于蝶筛区,6例位于上颌窦。通过CT对病变能够提供鼻窦肉瘤诊断的病例共27例（75.00%）,通过MRI能够提供鼻窦肉瘤诊断的病例共35例（97.22%）,两种检查方法有统计学差异（χ2=7.43,P〈0.05）。结论 CT可以较好地显示鼻窦骨质破坏,MRI能更清楚地显示鼻窦部位的侵犯范围,两者结合可为该病诊断和临床治疗提供更全面的影像信息。

CT and MRI Performance of 36 cases of sinuses sarcoma

Objective To investigate the manifestations of CT and MRI images of paranasal sinuses sarcoma, improve the accuracy of diagnosis. Methods Make retrospective analysis of our hospital from January 2008 to January 2014,36 patients with pathologically confirmed nasal sinuses sarcoma in patients with CT and MRI imaging data, to explore the value of imaging diagnosis. Results The MRI sarcoma typically presents with slight long T1 and slight long T2 signal,enhanced moderately enhanced. 36 cases of lesions center located in the sphenoid region, in maxillary sinus in 6 cas-es. The CT diagnosis of paranasal sinuses sarcoma of the lesion was a total of 27 cases（75.00%）,the MRI can provide the diagnosis of paranasal sinuses sarcoma in 35 cases（97.22%）,two methods had significant difference （χ2=7.43,P〈0.05）. Conclusion CT can effectively show the sinus bone destruction, MRI could clearly display the lesion＇s extent,the combination of image can provide more comprehensive information for the diagnosis and treatment of the Sinus.
