| 摘 要： | 目的:提高腮腺间隙原发病变影像诊断及鉴别诊断能力。方法:回顾性分析32例腮腺间隙原发病变的影像特征,包括25例良性肿瘤及肿瘤样病变,7例原发恶性肿瘤。结果:CT和MRI能显示病变累及的范围。多形性腺瘤局部含有丰富的纤维粘液样基质,在T2WI上呈高信号以及增强后明显强化。腮腺腺淋巴瘤多位于腮腺浅叶下极,表现为边界清楚的双侧或单侧多发的囊实性肿瘤,增强扫描早期明显强化。基底细胞瘤呈T1WI、T2WI低信号,增强后呈早期及延迟强化。1例血管淋巴管瘤和1例淋巴管瘤表现边界较清的弥漫性软组织肿块,具有"钻缝生长"特征。神经鞘瘤在MRI上信号不均匀,可见斑片状T2高信号,增强后不均匀明显强化。恶性肿瘤边界不清,浸润生长,T2WI呈低信号,增强后不均匀强化。其它病变缺乏影像学特征。结论:腮腺间隙原发病变有一定的临床及影像特征,术前CT和/或MRI检查,有利于病变的诊断、鉴别诊断和治疗方法的选择。
