图1 胰腺病灶超声声像图。图a、b低频探头检查(彩色标尺12 cm/s)示胰腺病灶位于体部,呈极低回声,边界清晰,边缘光整,边缘可见点条状血流信号;图c高频探头检查示胰腺病灶后方回声轻度增强
图2 胰腺病灶超声造影图像。图a示造影17 s病灶开始增强;图b示造影26 s病灶增强达峰,呈不均匀增强;图c示造影50 s,病灶造影剂开始廓清后15 s,病灶增强消退迟于胰腺
图3 胰腺病灶增强CT图像。病灶位于胰腺体部,呈稍高密度影,动脉期可见不均匀性强化;图a为平扫成像,图b为动脉期增强成像
图4 双肺结节增强CT图像。图a示肺结节(箭头所示)最大位于右肺中叶,大小约1.3 cm×1.2 cm;图b示双肺下叶多发结节(箭头所示),动脉期可见强化
图5 胰腺病灶正电子发射计算机断层显像图像。图示胰腺病灶代谢较胰腺轻度增高(最大标准摄取值约3.1)
图6 胰腺孤立性纤维性肿瘤病理图像。图a示病灶(★)边缘可见完整纤维包膜(HE×40);图b示镜下可见大量梭形细胞密集分布,其间可见血管外皮瘤样血管呈特征“鹿角样”分布(HE×200);图c示免疫标志物CD34(+)(免疫组织化学染色×100);图d示免疫标志物Bcl-2(+)(免疫组织化学染色×200)
图7 胰腺孤立性纤维性肿瘤患者术后第20个月复查双肺结节增强CT图像。图a示双肺结节较前进展,右肺结节最大者位于下叶后基底段,大小约2.1 cm×2.1 cm,增强可见强化(图b)
图8 胰腺孤立性纤维性肿瘤患者SCT-I10A治疗8个周期后复查双肺结节增强CT图像。图a示双肺结节较前稍增大,右肺结节最大者位于下叶后基底段,大小约3.3 cm×2.9 cm,增强可见强化(图b),随后多次复查病变趋于稳定
