摘要
目的探讨CT平扫及增强检查对腮腺常见良性肿瘤的诊断与鉴别诊的价值。方法回顾性分析经手术病理证实的32例良性肿瘤CT平扫及增强扫描资料,其中腮腺多形性腺瘤18例、腮腺腺淋巴瘤9例、基底细胞瘤5例,分析内容包括肿瘤部位、边界、CT平扫及增强特征等。结果腮腺多形性腺瘤18例,位于腮腺浅叶12例,后下象限5例;腮腺腺淋巴瘤9例位于腮腺浅叶后下象限8例,3例多发;基底细胞瘤5例,均位于浅叶,3例位于前下,2例位于后下。所有肿瘤边界均清晰。腮腺多形性腺瘤、腮腺腺淋巴瘤、基底细胞瘤动脉期强化CT值分别为(54.8±6.6,84.6±13.7,109.5±12.5)HU,多形性腺瘤与后两者差异有统计学意义(P<0.05);三者静脉期强化CT值分别为(49.3±6.4,71.7±14.8,92.5±11.9)HU,腮腺基底细胞瘤与前两者静脉期强化差异有统计学意义(P<0.05)。结论腮腺常见良性肿瘤的CT征象具有一定特征性,CT平扫及增强扫描对于腮腺良性肿瘤的定位定性诊断及鉴别诊断具有重要价值。
Objective To discuss the value of CT plain-scan and contrast-enhanced examination in the diagnosis and differential diagnosis of common benign parotid tumors. Methods CT findings of 18 cases ofparotid pleomorphic adenoma, 9 cases of adenolymphoma, 5 cases of parotid basal cell tumor proved by pathology were ranalyzed retrospectively, including the number, location, border, CT plain-scan and enhancement characteristics. Results 18 cases of parotid pleomorphic adenoma were single, located in the superficial lobe of the parotid gland （12 cases）, after the lower quadrant （5 cases）. The inferior quadrant in the parotid superficial lobe of 8 cases of 9, 3 cases of multiple; 5 cases basal cell carcinoma, were located in the superficial lobe, in the former 3 cases, 2 cases in the parotid gland lymphoma. All tumor boundaries were clear. Pleomorphic adenoma of the parotid gland, parotid gland lymphoma, basal cell tumor in arterial phase enhanced CT values were （54.8±6.6; 84.6 ± 13.7; 109.5±12.5） HU, pleomorphic adenoma after the difference was statistically significant （P 〈0.05）; 3 venous phase enhanced CT value （49.3 ± 6.4; 71.7±14.8; 92.5 ±11.9） HU, strengthen the parotid gland basal cell tumor and the first two venous phase difference was statistically significant （P 〈0.05）. Conclusions The parotid common benigns have characteristic CT signs; CT plain scan and enhanced scan have great value in the diagnosis and differential diagnosis of common benign parotid tumors.
