摘要
目的探讨CT对腮腺多形性腺瘤和腺淋巴瘤的诊断与鉴别诊断价值。方法回顾性对比分析经手术和病理证实的85例多形性腺瘤、18例腺淋巴瘤的临床资料和CT资料,并进行统计学处理。结果185例多形性腺瘤全部单发,男女比例接近,绝大多数位于腮腺非后下象限,形态规则或不规则,边界清楚,密度多不均匀,增强后呈缓慢延迟强化,约一半病灶出现强化范围扩大、实性成分强化不同步的特点;18例腺淋巴瘤几乎全部发生于老年男性,绝大多数位于腮腺后下象限,形态规则,边界清楚,密度多不均匀,增强后呈快进快退模式。2在瘤体最大径、左右侧分布、深浅叶分布、边界是否清晰、密度是否均匀、有无钙化、有无包膜外结节、有无下颌后静脉移位等方面差异无统计学意义(P>0.05);3在性别、年龄、是否吸烟、是否多发、肿瘤形态、象限分布、有无贴边血管征、有无胸锁乳突肌受压等方面差异有统计学意义(P<0.05);在平扫及双期增强CT值、各期CT值增加幅度及强化范围有无扩大等方面差异有统计学意义(P<0.05)。结论 CT对多形性腺瘤与腺淋巴瘤有较高的诊断价值,结合临床资料可有效将二者鉴别。
Objective To discuss the diagnosis and differential diagnosis value of CT on pleomorphic adeno-ma and adenolymphoma of parotid.Methods The CT findings of 85 patients with pleomorphic adenoma and 1 8 pa-tients with adenolymphoma confirmed by operation and pathology were analyzed retrospectively.Results ① 85 cases of pleomorphic adenoma were all single,male to female ratio was close,most lesions were located in the non-posterior-inferior quadrant of parotid gland,regular or irregular in shape with a clear boundary and heterogeneous density,and showed a slow delayed enhancement mode,about half of the lesions showed enhanced area expanded;1 8 cases of ade-nolymphoma occurred almost all in old men,most lesions were located in the posterior inferior quadrant,with a regular shape,clear boundary and heterogeneous density,the mode of enhancement was fast forward and rewind.②There were no statistically significant difference in the maximum diameter,side and lobe distribution,boundary,density,whether calcification,extra -capsular nodules,shift of mandibular vein （P 〉0.01 ）;③ there were statistically significant difference in gender,age,smoke or not,whether multiple,tumor shape,quadrant distribution,welt vascular symptoms, and also in plain and dual -phase enhanced CT values,each increment of CT values and enhancement area expanded or not （P 〈0.01 ）.Conclusion CT scan is valuable in the diagnosis and differential diagnosis of pleomorphic adeno-ma and adenolymphoma of parotid combined with the clinical data.
