医学论文范文:腮腺多形性腺瘤与腺淋巴瘤的CT表现对比分析
【摘要】 目的 探讨腮腺多形性腺瘤及腺淋巴瘤的CT表现特点。方法 收集2007年～2009年经手术病理证实的30例腮腺多形性腺瘤和35例腺淋巴瘤进行CT回顾性分析。 结果 30例多形性腺患者，其中病灶位于腮腺后下象限者2例(6%) ;多发者1 例(3%);增强CT值上升的平均值为(16.42±11.10)HU。35例腺淋巴瘤患者，其中病灶位于腮腺后下象限者32个(92%);多发者12 例(34%);增强CT值上升的平均值为(31.23±13.10)HU。 结论 在腮腺的良性肿块的鉴别诊断中，对于中老男性，发生于后下象限，病灶多发，血供丰富、增强后明显强化，应首先考虑诊断为腮腺腺淋巴瘤。

[Abstract] Objective To investigate CT manifestations of Parotid Pleomorphic Adenoma and Adenolymphoma. Methods CT findings of 30 cases with Parotid Pleomorphic Adenoma and 35 cases with Adenolymphoma confirmed surgically and pathologically during 2007~2009 were analysed retrospectively. Results 6%(2/30)Parotid Pleomorphic Adenoma were located in the posterior and inferior quadrant. Multiple synchronous Parotid Pleomorphic Adenoma in one side or bilateral parotids were found in 3%(1/30).30 cases with CT scanning increased (16.42±11.10)HU after contrast administration. 92%(32/35)adenolymphomas were located in the posterior and inferior quadrant. Multiple synchronous adenolymphomas in one side or bilateral parotids were found in 34% (12/35)35 cases with CT scanning increased (31.23±13.10)HU after contrast administration. Conclusion Differential diagnosis in the Parotid Benign Tumor，adenolymphomas of the parotid should be first considered when the mid-age male has lesions located in the posterior and inferior quadrant , especially when the lesion is multiple or bilaterally located.

腮腺混合瘤来源于腮腺上皮组织，是腮腺最常见的良性肿瘤，约占腮腺肿瘤的60～70%[1]。腺淋巴瘤是第二常见的腮腺良性肿瘤。尽管两者同属良性肿瘤，但未完整切除的多形性腺瘤半数可复发，复发者常沿神经分支分布，呈多发病变，手术切除更为困难。CT检查已成为常规有效的诊断方法。我们收集我院及广东省人民医院2007年1月～2009年6月具有完整CT和病理资料的30例多形性腺瘤和35例腺淋巴管瘤进行CT对比分析，探讨两者不同CT征象。提高腮腺良性肿瘤的鉴别诊断医.学全.在.线网站www.lindalemus.com。
