Fifty-eight consecutive cases of peridiaphragmatic fluid collections were correctly localized by computed tomography. The key to accurate localization of peridiaphragmatic fluid is identification of the hemidiaphragms. Pulmonary consolidation and pleural fluid collections lie adjacent and peripheral to the convexity of the hemidiaphragms. Free pleural fluid distends the posterior pleural recesses, important anatomic landmarks beneath the bases of the lungs. Intra-abdominal fluid collections lie adjacent and central to the convexity of the hemidiaphragms. On the right side intraperitoneal fluid is restricted from contact with the bare area of the liver by the coronary ligaments. It is concluded that peridiaphragmatic fluid collections can generally be readily identified if one is familiar with normal cross-sectional anatomy.
58例连续性膈周积液通过计算机断层扫描被准确地定位。膈周积液准确定位的关键在于识别半膈肌。肺实变和胸腔积液位于半膈肌凸面的相邻及外周部位。游离胸腔积液使后胸膜隐窝扩张，后胸膜隐窝是肺底部下方重要的解剖标志。腹腔内积液位于半膈肌凸面的相邻及中央部位。在右侧，冠状韧带限制了腹腔内液体与肝脏裸区接触。得出的结论是，如果熟悉正常的横断面解剖结构，通常可以很容易地识别膈周积液。
