摘　　要：目的 :评价CT在腮腺肿瘤中诊断及鉴别诊断的价值。方法 :通过回顾性分析 42例经术后病理证实的腮腺肿瘤的CT表现及其术前诊断 ,并与病理诊断进行对照分析。结果 :2 7例良性肿瘤中 ,有 2 4例CT表现为类圆形肿块 ,边界清楚 ,密度均匀 ,有 3例密度欠均匀 ,边界模糊 ;15例恶性肿瘤中 ,12例CT为边界不清 ,密度不均匀 ,3例密度均匀 ,边界较清晰。术前CT诊断对 85 71%腮腺肿瘤可作出定性诊断 ,但对其组织类型不能确认。结论 :大部分腮腺肿瘤可在CT中定性 ,但不能确认其组织学类型。Purpose: To discuss the pole of CT in the diagnosis and differential diagnosis of parotid neoplasms. Methods: A retrospective analysis of the CT examinations was performed in 42 patients with a histologically proven tumor of the parotid gland and compared with pathologic findings. Results: 24 cases were homogeneous density and with smooth margin in 27 benign tumors. 3 were inhomogeneous density and with ill-defined margin. 15 were malignant, 12 of them were heterogeneous density and with irregular margin, 3 were homogeneous density and with regular margin. 85.71% of parotid tumors could be differentiated malignant or benign by CT scan. Conclusion: CT can distinguish most of malignant parotid tumor from benign tumors, but can not categorize the histology types of the parotid tumors.
