目的探讨腮腺腺淋巴瘤CT表现与临床特点,以提高其诊断准确率。方法收集经手术及病理学证实的腮腺腺淋巴瘤患者11例,11例中男9例,女2例,分析病灶部位、数目、形态、大小、密度。结果 11例腮腺腺淋巴瘤中,5例病灶单发,6例多发,共20个病灶,其中13个(65%)病灶位于腮腺后下象限,CT显示病灶呈圆形、椭圆形及分叶状软组织肿块,边缘清晰,密度均匀7个,坏死囊变致密度不均匀13个;增强扫描病灶呈早期均匀强化,以中度强化为主,囊变区不强化。结论腮腺腺淋巴瘤好发于50岁以上的男性,当肿块发生于腮腺浅叶后下象限,边界清楚,特别是病灶多发并伴局灶性坏死,增强后中度以上强化时应首先考虑本病。 Objective To investigate the CT features and clinical features of parotid gland lymphoma in order to improve its diagnostic accuracy. Methods Eleven patients with parotid gland lymphoma confirmed by operation and pathology were collected, including 9 males and 2 females in 11 males and 2 females. The location, number, shape, size and density of lesions were analyzed. Results Of the 11 cases of parotid gland lymphoma, 5 lesions were single and 6 were multiple. There were 20 lesions, of which 13 lesions (65%) were located in the posterior parotid gland. CT showed lesions were round, oval and lobulated Like soft tissue mass with clear edge, 7 uniform density and 13 non-uniform density of necrotic cysts. The enhanced lesion showed homogeneous enhancement in the early stage, with moderate enhancement and no cystic area enhancement. Conclusion parotid gland lymphoma occurs in men over the age of 50, when the mass occurs in the lower quadrant of the parotid gland shallow border, the border is clear, especially in multiple lesions with focal necrosis, enhanced after more than moderate should first consider this disease.
