目的：探讨CT诊断腮腺多形性腺瘤的应用价值。方法对唐山市中医医院2009年1月~2014年10月疑似腮腺多形性腺瘤患者46例行CT平扫和增强扫描，对其检查结果与手术病理结果进行一致性检验分析。观察CT诊断腮腺多形性腺瘤的准确度、灵敏度、特异度。结果手术病理检查结果显示，腮腺多形性腺瘤44例，腮腺腺淋巴瘤1例，腮腺恶性肿瘤1例。CT检查结果显示，腮腺多形性腺瘤43例，腮腺腺淋巴瘤2例，腮腺恶性肿瘤1例。两种方法诊断腮腺多形性腺瘤的一致性较好（Kappa=0.71）。CT诊断腮腺多形性腺瘤的敏感度、特异度、准确度分别为97.7%、100.0%、97.8%。结论 CT诊断腮腺多形性腺瘤的敏感度、特异度、准确度较高，并能清楚显示肿瘤的形态、范围以及与周围结构的关系，能指导临床制订合理的手术方案。 CT增强扫描对肿物的良恶性鉴别具有重要的意义，可对术前的评估和预后提供科学依据。%Objective To explore the diagnosis value of CT for pleomorphic adenoma of parotid gland. Methods 46 cas-es of patients suspected pleomorphic adenoma of parotid gland in Tangshan Hospital of traditional Chinese Medicine from January 2009 to October 2014 were given CT plain scan and enhanced scan. The consistency of test results and surgical pathology results was analyzed. The accuracy, sensitivity, specificity of CT diagnosis of pleomorphic adenoma of parotid gland were observed. Results Operation pathological examination results showed that 44 cases had pleomor-phic adenoma of parotid gland, 1 case had parotid gland lymphoma, 1 case had malignant tumor of parotid gland. CT results showed that 43 cases had pleomorphic adenoma of parotid gland, 2 cases had parotid gland lymphoma, 1 case had malignant tumor of parotid gland. Consistency test (Kappa test) results showed that the two methods had good con-sistency (Kappa=0.71). The sensitivity, specificity, accuracy of CT diagnosis were 97.7%, 100.0%, 97.8%. Conclusion The sensitivity, specificity, accuracy of CT diagnosis of pleomorphic adenoma of parotid gland are higher, can clearly show the tumor morphology, range and the relationship with surrounding structures, can guide the clinical development of rational surgery program. Enhanced CT scan has important significance in differentiation for the benign and malig-nant neoplasm, can provide a scientific basis for the evaluation and prognosis of preoperative.
