摘　　要：目的:探讨CT检查在腮腺良恶性肿瘤鉴别诊断中的应用效果。方法:选取2019年4月—2022年4月睢宁县人民医院收治的腮腺肿瘤患者40例作为研究对象,均进行CT平扫与增强扫描,以病理诊断结果为“金标准”,分析CT检查对腮腺肿瘤的诊断效能(检出率、漏诊率、误诊率),比较良恶性腮腺肿瘤的CT征象。结果:CT结果显示,40例患者中,良性肿瘤23例,恶性肿瘤6例,检出率为72.8%(29/40),误诊率为5.0%(2/40),漏诊率为22.5%(9/40);CT与病理检查对不同类型腮腺肿瘤的检出率比较,差异无统计学意义(P>0.05)。良性腮腺肿瘤部位以浅叶为主,形态较为规则,且密度均匀,边界清晰,多数未出现钙化,囊变分级以1~2级为主,平扫和加强CT值较低;恶性肿瘤部位以深叶为主,形态不规则,密度不均匀,边界不清晰,多数出现钙化,囊变分级以3~4级为主,平扫和加强CT值较高。良恶性腮腺肿瘤的CT征象比较,差异有统计学意义(P<0.05)。结论:CT在腮腺良恶性肿瘤鉴别诊断中的应用价值显著,检出率较高,误诊率较低,能够清晰显示肿瘤部位、形态、边界、密度及强化程度等信息,但存在一定漏诊情况,针对疑似恶性腮腺肿瘤患者仍需进一步检查。Objective:To investigate the application effect of CT examination in differential diagnosis of benign and malignant tumors of parotid gland.Methods:A total of 40 patients with parotid gland tumors treated in Suining County People's Hospital from April 2019 to April 2022 were selected as the study subjects.All the patients received CT plain scans and enhanced scans.The pathological diagnosis result was used as the golden standard to analyze the diagnostic efficacy of CT examination on parotid gland tumors(detection rate,missed diagnosis rate,misdiagnosis rate).The CT signs of benign and malignant parotid gland tumors were compared.Results:CT results showed that,among the 40 patients,there were 23 cases of benign tumors and 6 cases of malignant tumors,the detection rate was 72.8%(29/40),the misdiagnosis rate was 5.0%(2/40),and the missed diagnosis rate was 22.5%(9/40).There was no significant difference between CT and pathological examination in the detection rate of different types of parotid gland tumors(P>0.05).Benign parotid tumors were mainly located in the superficial lobe,with a regular shape,uniform density and clear boundary,most of them had no calcification,and the cystolization grade was mainly grade 1-2,with low plain scan and enhanced CT value.While the malignant tumors were mainly located in the deep lobe,with irregular shape,uneven density and unclear boundary,most of them had calcification,and the cystolization grade was mainly grade 3-4,with high plain scan and enhanced CT value.The CT signs of benign and malignant tumors showed a statistically significant difference(P<0.05).Conclusion:CT has a significant application value in the differential diagnosis of benign and malignant tumors of parotid gland,with high detection rate and low misdiagnosis rate,which can clearly display tumor location,morphology,boundary,density and degree of intensification,but there is a certain missed diagnosis,and further examination is still required for patients with suspected malignant parotid gland tumors.
