神经鞘瘤与神经纤维瘤超声影像特征对比及诊断一致性分析OA

Objective:To explore the contrast and consistency analysis of ultrasound imaging features between schwannoma and neurofibroma.Methods:This study adopted a continuous inclusion method and selected 39 patients with schwannoma from our hospital between January 2020 and November 2024 as the schwannoma group and 41 patients with neurofibroma as the neurofibroma group.Evaluated the tumor characteristics of two groups of patients using ultrasound examination,and consistency analysis was performed based on clinicopathologic features.The Kappa coefficient was used to evaluate the consistency of ultrasound imaging features and clinicopathologic features;and analyze the value of joint diagnosis through ROC curve analysis.Results:Compared with the neurofibroma group,there were significant differences in the smallest diameter,location(depth),maximum diameter,unclear boundary,Ki-67,irregular shape,cystic-solid nature,spindle shape,palisade,envelope,cystic component(none)and blood flow grade 3 in the schwannoma group(P<0.05).The Kappa analysis results showed a strong consistency between ultrasound characteristic diagnosis and clinical pathological diagnosis(Kappa=0.791).The ROC curve results showed that the AUC value(0.804),sensitivity(94.87%),and accuracy(80.00%)of clinicopathologic features combined with ultrasound imaging features were significantly higher than those of a single diagnostic method,indicating that combined diagnosis had higher accuracy and sensitivity.Conclusion:This study compared the ultrasound imaging features and clinical pathological features of schwannoma and neurofibroma,and found a strong consistency between ultrasound imaging features and clinical pathological diagnosis(Kappa=0.791),indicating that ultrasound examination has high reliability in the diagnosis of schwannoma.In addition,the AUC value,sensitivity,and accuracy of the combined diagnosis of ultrasound imaging features and clinicopathologic features were higher than those of a single diagnostic method,further confirming the important value of the combined application of the two in the diagnosis of schwannoma.Therefore,ultrasound examination can serve as an important auxiliary tool for clinical diagnosis of schwannoma,and combining it with clinicopathologic features can significantly improve the accuracy and sensitivity of diagnosis.
