摘要 目的:分析腮腺肿瘤CT影像学表现及与病理学结果对照。方法:回顾性收集2017年2月-2019年10月在本院经病理确诊的61例腮腺肿瘤患者的临床资料。对患者所得图像进行分析,比较不同性质腮腺肿瘤的CT影像学表现(病灶分布部位、形态、密度、边缘、强化程度、邻近组织结构、侵犯程度、囊变坏死情况、淋巴结肿大等)。结果:良性肿瘤病理:切面呈灰白淡褐色,边界清楚,质地柔软;镜下:肿瘤细胞多为腺导管上皮细胞和肌上皮细胞组成。恶性:切面为灰褐色,边界不清,质脆,无包膜,有坏死。镜下:片状、腺囊状,部分区域肿瘤细胞表现为细条索状,为浸润性生长,压迫周围组织。CT表现:良性腮腺肿瘤多数生长在浅部,肿瘤形态规则、密度均匀,边界清楚,少数患者存在淋巴结肿大(8.82%)以及囊变(41.17%)情况,肿瘤为轻、中度强化;恶性腮腺肿瘤常生长于深部,肿瘤形态不规则、边界不清楚、88.89%患者可见淋巴结肿大,92.59%可见囊变,肿瘤多为明显强化。结论:不同性质腮腺肿瘤CT影像学表现存在明显差异,基于病理基础结合影像学征象进行分析,有助于提高诊断准确率。
