The liver is fixed in the right upper quadrant of the abdomen by a complex system of peritoneal reflections, known as ligaments. Embryologic evaluation shows that these ligaments, apparently unrelated, are part of a continuum: the ventral mesogastrium. The areolar tissue within the ligaments constitutes a potential space that links the liver with other viscera and with extraperitoneal sites, allowing direct spread of inflammatory or malignant diseases between these organs and spaces. Knowledge of the normal and pathologic appearance of the ligaments is necessary in order to diagnose dissemination of pathologic processes along them. Computed tomography (CT) is the imaging modality of choice for studying ligamentous involvement by disease. On CT scans, occupation or obliteration of ligamentous fat planes by fluid collections or areas of soft tissue with increased attenuation are the signs of direct spread of disease.
肝脏通过一个复杂的腹膜反折系统固定在腹部右上象限，该系统即所谓的韧带。胚胎学评估显示，这些看似无关的韧带是一个连续结构的一部分：腹侧胃系膜。韧带内的疏松结缔组织构成了一个潜在间隙，该间隙将肝脏与其他内脏以及腹膜外部位相连，使得炎症或恶性疾病能够在这些器官和间隙之间直接蔓延。为了诊断沿韧带扩散的病理过程，了解韧带的正常和病理表现是必要的。计算机断层扫描（CT）是研究疾病对韧带累及情况的首选成像方式。在CT扫描上，液体聚集或软组织密度增加区域占据或闭塞韧带脂肪平面是疾病直接蔓延的征象。
