腹部计算机断层扫描的淋巴结大小的正常上限的报告从6到20毫米不等。建立一个上限的特定位置的淋巴结大小，类似于已报告的纵隔淋巴结，寻求。 在130例不太可能有腹部淋巴结肿大的患者中测量淋巴结的短轴直径。 定义了七个位置，并记录了每个位置的最大节点测量值。 使用组织学分析和非参数统计方法确定每个区域最大淋巴结大小的阈值。 正常范围的位置上限如下：脚后间隙，6 mm;心旁间隙，8 mm;胃肝韧带，8 mm;主动脉旁上部区域，9 mm;门腔间隙，10 mm;肝门，7 mm;主动脉旁下部区域，11 mm。主动脉旁下部淋巴结短轴测量大于11 mm为异常。 在其他位置，如果超过所确定的阈值，则小于1 cm的节点可能是异常的。
Reports of the upper limits of normal for lymph node size at abdominal computed tomography have varied from 6 to 20 mm. Establishment of an upper limit for node size by specific location, analogous to that which has been reported for mediastinal lymph nodes, was sought. Short-axis diameters of the lymph nodes were measured in 130 patients who were not likely to have enlarged abdominal lymph nodes. Seven locations were defined, and the largest nodal measurement for each was recorded. Histographic analysis and nonparametric statistical methods were used to determine threshold values for the maximum node size in each region. The upper limits of normal by location were as follows: retrocrural space, 6 mm; paracardiac, 8 mm; gastrohepatic ligament, 8 mm; upper paraaortic region, 9 mm; portacaval space, 10 mm; porta hepatis, 7 mm; and lower paraaortic region, 11 mm. Lower paraaortic lymph nodes larger than 11 mm by short-axis measurement are abnormal. In other locations, nodes smaller than 1 cm may be abnormal if the determined thresholds are exceeded.
