摘要
目的：探讨腮腺肿瘤的CT诊断价值。方法：回顾性分析经手术及病理证实的腮腺肿瘤20例，其中良性肿瘤12例，恶性肿瘤8例。结果：12例良性肿瘤中，形态规则、边界清晰者11例，边界不清者1例；其中8例行增强扫描，均表现为轻至中度强化，其中密度均匀者5例，密度不均者3例。8例恶性肿瘤中，形态不规则、边界不清并伴邻近组织器官受侵者7例，边界清楚、形态规则者1例；其中6例行增强扫描，均见不同程度强化，肿瘤密度均匀者1例，密度不均者5例，其中2例中心可见大片低密度坏死；8例恶性肿瘤中，4例合并颈部淋巴结肿大，3例面神经受累。结论：CT扫描对腮腺肿瘤的诊断及鉴别诊断具有重要价值。
Objective：To analyze CT characteristics of benign and malignant parotid tumors. Methods：CT features of 20 patients with parotid tumors proved pathologically and clinically were reviewed. There were 12 benign tumors and 8 malignant tumors. Results：Of 12 benign tumors, 11 were regular and well-defined, 1 had indistinct margin. Enhanced CT scanning was performed in 8 cases, and all lesions showed slightly and middle enhancement. Homogeneous density was found in 5 and heterogeneous density in 3 cases. Of 8 malignant tumors, 7 were irregular with indistinct margin and infiltrated into the adjacent structures, 1 lesion showed clear margin and regular in shape. Enhanced CT scanning was performed in 6 cases and all lesions showed enhanced. There were homogeneous density in 1 and heterogeneous density in 5 eases, of which large central necrosis was seen in 2. Of the 8 malignant tumors, enlarged cervical lymph nodes were found in 4 cases and the facial nerve was involved in 3 cases. Conclusion：CT plays an important role in detecting and distinguishing benign and malignant parotid tumors.
