Two cases of incidentally detected aneurysms involving the portal venous system are described with emphasis on gray-scale and color Doppler ultrasonographic (US) findings. Appearing on US as anechoic masses showing direct luminal continuity with the right portal vein and superior mesenteric vein, the lesions displayed spectral findings characteristic of portal venous system on color Doppler US. Dynamic helical computed tomography (CT) demonstrated simultaneous enhancement with the portal system, while the aneurysms were hypointense owing to flow void on T1-weighted spin-echo magnetic resonance (MR) images.
本文描述了两例偶然发现的累及门静脉系统的动脉瘤，重点介绍了灰阶和彩色多普勒超声（US）检查结果。这些病变在超声上表现为无回声肿块，与右门静脉和肠系膜上静脉有直接的管腔连续性，在彩色多普勒超声上显示出门静脉系统的频谱特征。动态螺旋计算机断层扫描（CT）显示与门静脉系统同时强化，而在T1加权自旋回波磁共振（MR）图像上，动脉瘤因血流空洞而呈低信号。
