图1 腹部包块超声图像。彩色多普勒血流显像示肿块内可见条索状血流信号
图2 腹部包块超声造影图像。图a示19 s时,右上腹肿块可见蜂窝状不均匀快速强化增强;图b示53 s时廓清呈低增强,病灶呈现"快进快出"表现
图3 腹部包块MRI图像。图示右侧腹腔不规则肿块,边缘模糊,平扫呈稍长T1稍长T2混杂信号,增强不均匀强化,与胆囊底、邻近肠管关系密切。图a为T1加权像;图b为T2加权像;图c为增强图像
图4 腹部包块的CT增强重建冠状位图像。图示右侧腹腔不规则肿块,边缘模糊,增强不均匀强化,与胆囊底部、邻近肠管分界不清
图5 胆囊多形性巨细胞肉瘤样癌术后病理及免疫组化图像。图a示镜下见弥漫性显著异型的肉瘤样细胞浸润性生长,部分为瘤巨细胞,病理性核分裂像易见(HE ×200);图b示免疫组化标记部分肉瘤样细胞PCK(+),提示肿瘤细胞为上皮源性;图c示免疫组化标记Vimentin(+),提示肿瘤细胞为间叶源性
