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。
Objective: To evaluate the value of CT in the diagnosis and differential diagnosis of parotid tumors. Methods: CT findings and preoperative diagnosis of 42 parotid tumors confirmed by postoperative pathology were retrospectively analyzed and compared with the pathological diagnosis. RESULTS: Twenty-four of 27 benign tumors showed cystoid masses with clear border and uniform density. The density of three lesions was less uniform and the border was blurred. CT was found in 12 of 15 malignant tumors with unclear boundary , Uneven density, 3 cases of uniform density, the border more clearly. Preoperative CT diagnosis of 85 71% of parotid tumors can make a qualitative diagnosis, but its type can not be confirmed. Conclusion: Most parotid tumors can be characterized by CT, but their histological type can not be confirmed.
