醫(yī)學論文范文:腮腺多形性腺瘤與腺淋巴瘤的CT表現(xiàn)對比分析
【摘要】 目的 探討腮腺多形性腺瘤及腺淋巴瘤的CT表現(xiàn)特點。方法 收集2007年～2009年經(jīng)手術(shù)病理證實的30例腮腺多形性腺瘤和35例腺淋巴瘤進行CT回顧性分析。 結(jié)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%) ;多發(fā)者1 例(3%);增強CT值上升的平均值為(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個(92%);多發(fā)者12 例(34%);增強CT值上升的平均值為(31.23±13.10)HU。 結(jié)論 在腮腺的良性腫塊的鑒別診斷中，對于中老男性，發(fā)生于后下象限，病灶多發(fā)，血供豐富、增強后明顯強化，應首先考慮診斷為腮腺腺淋巴瘤。

[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.

腮腺混合瘤來源于腮腺上皮組織，是腮腺最常見的良性腫瘤，約占腮腺腫瘤的60～70%[1]。腺淋巴瘤是第二常見的腮腺良性腫瘤。盡管兩者同屬良性腫瘤，但未完整切除的多形性腺瘤半數(shù)可復發(fā)，復發(fā)者常沿神經(jīng)分支分布，呈多發(fā)病變，手術(shù)切除更為困難。CT檢查已成為常規(guī)有效的診斷方法。我們收集我院及廣東省人民醫(yī)院2007年1月～2009年6月具有完整CT和病理資料的30例多形性腺瘤和35例腺淋巴管瘤進行CT對比分析，探討兩者不同CT征象。提高腮腺良性腫瘤的鑒別診斷醫(yī).學全.在.線網(wǎng)站m.quanxiangyun.cn。
