摘要 目的提高对腮腺基底细胞腺瘤CT表现的认识,探讨多层螺旋CT(MDCT)的诊断价值。方法回顾性分析12例CT平扫及增强扫描后经手术病理证实的腮腺基底细胞腺瘤的部位、数目、大小、形态、边界、密度及强化特征。结果(1)男4例,女8例,其中50-59岁女性7例(58.0%);(2)12例共14个病灶,11例单发,1例单侧3个病灶;(3)病灶位于浅叶者12个,2个病灶跨深浅两叶;(4)病灶最大径均〈3em,其中〈1cm者5个,1—2cm者6个,〉2cm者3个;(5)所有的病灶边界均清楚;病灶边缘光整者13个,不光整者1个;(6)病灶内密度均匀者3个,其中2个见于〈1cm的病灶;病灶中央规则囊变者4个,不规则囊变者7个;其中5个病灶囊变区〉50%;(7)增强后所有病灶均明显强化,强化幅度I〉40Hu。结论病灶较小、单发、位于腮腺浅叶、边界清楚、边缘光整、病灶易囊变及强化明显为腮腺基底细胞腺瘤较为特征性的CT表现,认识这些CT表现结合患者性别、年龄有助于做出正确诊断。 Objective To investigate MSCT findings of CT features of basal cell adenomas in the parotid gland, and improve its diagnostic value. Methods 12 cases plain and enhanced CT findings of basal cell adenomas in the parotid gland were retrospectively analyzed for their position, numbers, size, shape, edge, density and enhancement features,which were all verified pathologically after surgery. Results ( 1 ) There were 4 males and 8 females, of which 7 females were in the age of 50 - 59;(2) There were 14 lesions in 12 cases, 11 cases were single and 1 case was unilateral multiple(3 lesions) ; (3) 12 lesions were situated in superficial lobe of the parotid gland,and 2 lesions were situated between superficial lobe and deep lobe of the parotid gland; (4) The maximum diameter of all lesions were 〈 3cm, of which 5 lesions were 〈 1 cm, and 6 lesions were 1 - 2cm, and 3 lesions were 〉 2cm; (5) The bounda- ry of all lesions were clear;The edge of 13 lesions were smooth and llesion was aot smooth; (6) The density of 3 lesions were uniform,of which the diameter of 2 lesions were 〈 lcm. There were 4 lesions showed a regular cystic zone in the center,and 7 lesions showed a irregular cystic zone in the center;The area of cystic zone were 〉50% in 5 lesions; (7)All of 14 lesions were enhanced obviously in enhanced CT scans. Increase of CT values were ≥40HU. Conclusion Single less lesions situated in superficial lobe of parotid gland,with clear boundary,smooth edge, cystic zone in the lesions, and enhanced obviously were the CT features of basal cell adenomas. Recognizing this CT features combined with the patients' gender and age could make for a definite diagnosis.
