摘要
目的:明确恶性淋巴瘤累及腹部淋巴结的CT增强表现特点及解剖分布,以提高定性、定位诊断的准确性。材料和方法:对41例恶性淋巴瘤,包括Hodgkin病(HD)15例及非Hodgkin淋巴瘤(NHL)26例,采用CT增强扫描,观察淋巴结的大小、形态、密度及解剖分布。结果:增大淋巴结的CT增强密度,HD中,86.7%为均匀密度,13.3%为均匀与不均匀密度并存;NHL中,73.1%为均匀密度,26.9%为均匀与不均匀密度并存。HD及NHL均优势累及腹主动脉周围、肾旁前间隙及肝十二指肠、肝胃韧带淋巴结。常同时使2个部位以上的淋巴结受累。结论:CT增强扫描可一定程度地显示恶性淋巴瘤的大体病理特点,存在2种强化类型,恶性淋巴瘤累及腹腔。
