摘要
目的:探讨MSCT对腮腺混合瘤和腺淋巴瘤的诊断及鉴别诊断价值。方法 :回顾性分析经手术后病理证实的25例腮腺混合瘤及18例腮腺腺淋巴瘤的CT表现,比较两者的影像学特点并进行统计学分析。结果:混合瘤多发于年轻患者,病灶单发,多位于腮腺叶非后下极,形态规则或不规则,边界清楚,密度可均匀或不均匀,伴坏死囊变,囊变常为大片状;腺淋巴瘤多发于中老年男性,单发或多发,多位于腮腺浅叶后下极,形态规则或呈浅分叶状,边界清楚,密度可均匀或不均匀,可伴裂隙样囊变,可见血管贴边征。2组在发病年龄、性别、病灶数目、象限、形态、囊变方式及血管贴边征等方面差异均有统计学意义(均P<0.05)。结论:MSCT对腮腺混合瘤及腺淋巴瘤具有一定的临床诊断价值,结合病史有助于提高两者的鉴别诊断水平。
Objective：To discuss the diagnosis and differential diagnosis value of MSCT on pleomorphic adenoma and ade-nolymphoma of parotid by investigating the imaging manifestations of CT. Methods：the CT characteristics of 25 cases of pleo-morphic adenoma and 18 cases of adenolymphomas in the parotid gland confirmed by histological pathology in our hospital were studied retrospectively. Results：25 cases of pleomorphic adenoma of parotid occurred in young patients,most lesions were located in the non-posteriorinferior quadrant of parotid gland,regular or irregular in shape with a clear boundary and heteroge neous or inhonmogeneous （cystosolid） density with large cysts. 18 cases of adenolymphoma occurred almost all in old men,lesions in unilateral sides or bilateral sides,most lesions were located in the posterior inferior quadrant,with a regular shape and clear boundary heterogeneous or inhonmogeneous （cystosolid） density with fracture cysts. Small vessels could be seen in or around the tumor. There were singificant differences （P〈0.05）,between pleomorphic adenoma and adenolymphoma of parotid in age,gender, number of morbidity,the incidence ratio quadrant,morphology,the ways of cyst and small vessels in or around the tumor. Con-clusion：There are some characteristics of CT in pleomorphic adenoma and adenolymphoma of parotid. Imaging characteristics combined with clinical materials can improve the diagnosis and differential diagnosis on pleomorphic adenoma and adenolym-phoma of parotid gland.
