目的分析并总结常规颅脑CT诊断副鼻窦病变情况及其应用价值。方法随机性抽取2006年12月至2010年12月期间的500张常规颅脑CT片,与原诊断进行对照,并通过对鼻窦的显示结果与疾病的诊断进行综合分析。结果本组全部病例筛窦与蝶窦的显示率均为100%,显示分别位于1～3层面和1～2层面;额窦部位的显示率为97.8%,显示位于2～5层面;上颌窦显示率仅仅为18.6%,显示位于1～5层面。鼻窦病变的总阳性率为22.9%,其中炎症、肿瘤、囊肿瘤与外伤所占百分比分别为83.0%、7.4%、1.2%和9.2%。鼻窦总漏诊率为62.0%,炎症占所有漏诊病例的76.6%,颅脑CT报告正常患者占漏诊病例的60.0%。结论常规颅脑CT对于诊断鼻窦病变具有重要的参考价值,应引起影像医师的高度重视。
Objective To analyze and summarize the diagnosis of paranasal sinus lesions by conventional brain CT and its application value. Methods A random sample of 500 conventional brain CT pictures taken from December 2006 to December 2010 was collected and compared with the original diagnosis. The results of the sinus and the diagnosis of the disease were comprehensively analyzed. Results All the cases showed ethmoid sinus and sphenoid sinus in 100% of the cases, which showed that they were located on the first to third levels and the second to fifth levels respectively. The display rate of the frontal sinus was 97.8% The display rate is only 18.6%, showing that in the 1 to 5 level. The total positive rate of sinus lesions was 22.9%, of which 83.0%, 7.4%, 1.2% and 9.2% respectively were inflammation, tumor, cystadenoma and trauma. Total misdiagnosis rate of sinus was 62.0%, inflammation accounted for 76.6% of all misdiagnosed cases, and 60.0% of the cases missed by brain CT were reported as normal. Conclusion Conventional craniocerebral CT is an important reference value for the diagnosis of sinus diseases, which should be paid great attention to by imaging physicians.
