Fluid collections in the lower pleural cavity and upper abdominal cavity may sometimes appear similar on computed tomography. Lateral displacement of the diaphragmatic crus and interposition of fluid between the crus and vertebral column indicate an intrapleural component. Demonstration of fluid anterior to the crus establishes an intraperitoneal component. Medial location of the posterior recess of the fluid collection and the intercostal bulging of its lateral margin suggest a pleural effusion.
下胸腔和上腹腔的液体聚集在计算机断层扫描上有时可能看起来相似。膈脚的侧向移位以及膈脚与脊柱之间存在液体提示有胸腔内成分。在膈脚前方显示有液体则提示有腹腔内成分。液体聚集后隐窝的内侧位置及其外侧边缘的肋间膨出提示胸腔积液。
