腮腺腺淋巴瘤多层CT诊断与病理对照

Multi-slice CT diagnosis and pathological correlation of parotid adenolymphoma

目的:分析腮腺腺淋巴瘤临床表现及CT影像,探讨CT对其的诊断及鉴别诊断价值。方法:回顾性分析2014~2017 年我院手术病理证实的15例腮腺腺淋巴瘤患者的临床表现及CT影像。结果: 15个病例共30个瘤灶,单发瘤灶8例(53.33%),多发瘤灶7例(46.67%);瘤灶主体位于浅叶13例(86.67%),位于深叶2例(13.33%);有囊性变6例(40.00%),无囊性变9例(60.00%);所有瘤灶均无钙化;11例(73.33%)有长期吸烟史。肿瘤实性部分平扫CT值36~52(45±10) Hu,动脉期CT值72~127(105±18) Hu,延迟期CT值70~93(81±9) Hu,强化程度减退<20 Hu者6例,20~40 Hu者7例,>40 Hu者2例,平均减退(23±13) Hu。结论:根据腮腺腺淋巴瘤临床表现及CT影像,可以为术者提供可靠的参考依据。

Objective: To analyze the clinical manifestations and CT images of parotid adenolymphoma ,and to explore the CT diagnosis and differential diagnosis of parotid adenolymphoma . Methods: Fifteen cases with parotid adenolymphoma confirmed by operation and pathology from 2014 to 2017 were selected.The clinical manifestation and CT images were analyzed. Results: There were thirty tumors in 15 cases,including 8 cases( 53.33%) single tumors,7 cases(46.67%) multiple tumors,13 cases(86.67%) superficial ones,2 deep ones (13.33%),6 cystic ones(40.00%) and 9 cases(60.00%) non-cystic ones.All tumors had no calcium changes,and 11 cases(73.33%) had a long history of smoking.The CT values of solid partial plain scan were 36-52(45±10)Hu,arterial phase were 72-127(105±18) Hu,delayed phase were 70-93(81±9) Hu.The degree of enhancement decreased in 6 cases less than 20 Hu,7 cases were 20-40 Hu,and 2 cases larger than 40 Hu,with an average decrease of (23±13) Hu. Conclusion: According to the clinical manifestations and CT images of parotid adenolymphoma ,improve judgement accuracy can provide reliable reference for clinical surgery.
