摘　　要：目的:对比分析伴有炎症和不伴有炎症表皮样囊肿病例的临床特点和超声表现,探讨超声诊断伴有炎症的表皮样囊肿的特征性影像。方法:回顾性分析2015年12月至2020年10月在山东大学第二医院行超声检查的272例浅表组织病变患者的临床资料。所有患者病变组织均经手术切除,病理结果为表皮样囊肿。按照病理结果是否伴有炎症分为两组,对比其临床特点和超声表现。结果:两组病灶处的皮肤颜色、与皮肤的关系、形态、超声后方回声、长/厚、CDFI及超声诊断准确率等方面差异均有统计学意义(P<0.05)。多因素回归分析结果显示,皮肤颜色异常和超声显示病变伴有血流信号有助于诊断伴有炎症的表皮样囊肿。结论:超声对伴有炎症的表皮样囊肿容易误诊;结节表面皮肤颜色异常、超声显示结节内部和/或周边伴有血流是诊断伴有炎症的表皮样囊肿的重要特征,可以帮助提高诊断准确率。Objective:The aim of this study was to explore the characteristic images epidermoid cysts(EC)with and without inflammation by comparing and analyzing their clinical features and ultrasonic manifestations.Methods:A total of 272 cases were included and retrospectively analyzed in the Second Hospital of Shandong University from December 2015 to October 2020.Lesions were examined by ultrasound before operation and pathologically diagnosed as EC after operation.All cases were divided into two groups:inflammation group and non-inflammation group based on pathological results.Clinical and ultrasonic features were compared between the two groups.Results:There were statistically significant differences between the two groups in the skin color,relationship with the skin,morphology,posterior echo,length/thickness,CDFI and ultrasound diagnosis accuracy of the lesion(P<0.05).Variables with statistical significance in univariate analysis(P<0.05)were included in the multivariate logistic regression model as independent variables.Multivariate analysis showed that abnormal skin color and lesions with by blood flow signals were risk factors for the diagnosis of inflammatory epidermoid cysts.Conclusion:The ultrasound diagnosis of EC with inflammation is more likely to be misdiagnosed.Abnormal skin color and lessio with blood flow signals are important ultrasound and clinical features for the diagnosis of EC,which can help improve the diagnosis rate of EC accompanied by inflammation.
