Abstract
Septic thrombi, such as those observed in pylephlebitis and Lemierre's syndrome, are characterized by portal vein thrombosis and venous thrombosis with bacterial infection. Although radiographic findings of septic thrombus on contrast-enhanced computed tomography have been well described, no report has described the characteristics of non-contrast-enhanced computed tomography. We describe a case series of septic thrombophlebitis exhibiting intravascular hypo- and hyper-attenuation on non-contrast-enhanced computed tomography. These radiographic features reflect the pathophysiology of septic thrombus, and therefore, it is important and useful to evaluate thrombus attenuation on non-contrast-enhanced computed tomography.
摘要
感染性血栓，如门静脉炎和勒米埃雷氏综合征中观察到的血栓，其特征为门静脉血栓形成和静脉血栓形成伴细菌感染。尽管对比增强计算机断层扫描对感染性血栓的放射学表现已有很好的描述，但尚无报告描述非增强计算机断层扫描的特征。我们描述了一系列表现为非增强计算机断层扫描下血管内低和高衰减的感染性血栓性静脉炎病例。这些影像学特征反映了感染性血栓的病理生理学，因此，评估非增强计算机断层扫描下血栓的衰减非常重要且有用。
