腮腺腺淋巴瘤的CT表现(附9例报告)

CT features of parotid adenolymphoma(report of 9 cases)

目的：探讨腮腺腺淋巴瘤的CT表现特点。方法：回顾性分析经手术病理学证实的腮腺腺淋巴瘤患者9例。观察病灶数目、部位、大小、形态、密度，将腮腺矢状面分成4个象限。结果：9例患者，15个病灶，病灶位于腮腺后下象限者10个，1例双侧均为腮腺腺淋巴瘤，14个病灶边缘清楚，病灶大小1．1～3．2cm，平均CT值48HU。结论：50岁以上的男性患者，CT显示腮腺浅叶的后下象限病灶，边界光整、多发时应首先考虑腮腺腺淋巴瘤可能。

Objective： To investigate the characteristics of CT manifestations of adenolymphomas of the parotid gland. Methods： The CT characteristics of 9 cases （15 lesions） of adenolymphomas confirmed by pathology were studied retrospectively. They were 8 men and 1 women ranging in age 53 -78 years （mean age 65）. The analysis of imaging characteristics included the number, position, size, shape, density, The parotid gland were divided into 4 quadrants in sagittal section for diagnosis. Results： Fifteen lesions were found. Among 10 lesions were located in the posterior and inferior quadrant. Multiple synchronous adenolymphomas bilateral parotids were found in 1 patients. The margins in 14 lesions were well defined. The sizes of the lesions ranged in 1.1 - 3.2cm, and the mean CT value of them was 48HU. Conclusion： Adenolymphomas of the parotid gland should be first considered when the male patient over 50 years has lesions located in the posterior and inferior quadrant area with well defined margin, especially when the lesion is multiple.
