目的探讨CT对腮腺良恶性肿瘤的定性诊断及鉴别诊断价值。方法回顾性分析72例腮腺肿瘤患者CT平扫及增强图像。分析比较肿瘤的分布、形态、密度、边缘、囊变坏死、强化程度、颈部淋巴结肿大情况,并与最终病理结果对照。结果病灶80个,其中良性59个,恶性21个。良性组：42个(71.2%)位于腮腺浅叶、形态规则、密度均匀,62.7%边缘清楚,57.6%呈轻中度强化,2例良性肿瘤出现颈部淋巴结肿大,术后病理均炎性肿块。恶性组：12例(57.1%)位于腮腺深叶或跨深浅两叶,15例(71.4%)表现为形态不规则、密度不均匀,81%边缘不清,71.4%增强后明显强化,9例出现颈部淋巴结转移。两组肿瘤形态、边缘、密度、囊变坏死、淋巴结转移差异均有统计学意义(P<0.05),两组发生部位、强化程度差异无统计学意义( P>0.05)。结论 CT可用于定性诊断大部分腮腺良恶性肿瘤。

Objective To explore the clinical value of multi-slice CT in distinguishing between benign parotid tumors and malignant parotid tumors. Methods CT scanning images of 72 parotid tumor patients were analyzed. The location, shape, density, edge, cystic necrosis and degree of enhancement of the tumors were analyzed, de-gree of cervical lymph node swelling were analyzed, and all the analysis results were compared to pathological re-sults. Results 80 lesions were diagnosed in tumors, among which 59(73. 8%) lesions were benign tumors and 21 (26. 2%) lesions were malignant tumors. The CT images of benign tumors showed that 42(71. 2%) of them were located in the superficial lobe and with regular shape and uniform density;62.7% of them had clear edge;57 . 6%of them showed mild or moderate enhancement. 2 cases of benign tumors presented cervical lymph node swelling, which were proved to be pathological inflammatory mass after operation. Whereas in the CT images of malignant tumors 12( 57. 1%) of them were located in the deep lobe or in both of the superficial lobe and the deep lobe. 15 (71. 4%) of them had irregular shape and uneven density. 81% of them had unclear edge. 71. 4% of malignant tumors were significantly enhanced. 9 cases of malignant tumor were with cervical lymph node metastasis. There was statistical difference between the shape, edge, density, cystic necrosis, degree of enhancement and cervical lymph node metastasis of the two groups of tumors(P<0.05), while the location and the degree of enhancement of the two groups of tumors showed no statistical difference ( P>0.05 ) . Conclusion Most of benign and malignant parotid tumors can be correctly diagnosed by analyzing multi-slice CT images.
