摘要 目的探讨脑内原发性淋巴瘤的CT、MRI征象,提高其诊断水平。方法回顾性分析18例经病理证实的脑内原发性淋巴瘤的CT、MRI表现,分析病灶的分布、形态、密度、信号特点及强化特征。结果 18例患者中,单发病灶12例,6例多发,均位于幕上,位于额顶叶深部10例,额顶叶及颞叶灰白质交界区4例,基底节区2例,枕叶1例,顶枕叶交界处1例,其中1例病灶跨中线生长,累及胼胝体8例,病灶多呈类椭圆形、团块状或不规则形,CT平扫多为等或稍高均匀密度肿块,T1WI呈稍低或等信号,T2WI呈稍高、高或等信号,DWI多为稍高或高信号。增强后病变多呈中度及明显均匀性强化,内囊变、坏死及钙化少见,7例病灶可见开口包绕邻近血管的脐凹征,5例病灶边缘不规则,瘤周水肿及占位征象较轻。结论原发性脑淋巴瘤的CT、MRI表现有一定的特征性,但与其它脑内肿瘤有相似之处,确诊主要依靠病理检查。
