The computed tomographic characteristics of the pleural empyema were illustrated in three patients. A typical empyema is characterized by lower thorax location, oblong and round contour in cross-section, homogeneous content with or without air spaces or air-fluid levels, regularly thin wall opposing the chest wall (a rim sign), irregularly thick wall opposing the lung parenchyma, and smooth inner and outer margins. By application of such computed tomographic criteria, a pleural empyema can be readily distinguished from a peripheral lung abscess.
三名患者的胸膜积脓的计算机断层扫描特征得到了展示。典型的胸膜积脓表现为位于下胸部，横断面呈椭圆形或圆形，内容物均匀，有或无气腔或气液平面，与胸壁相对的壁层胸膜规则变薄（边缘征），与肺实质相对的壁层胸膜不规则增厚，以及内、外边缘光滑。通过应用这些计算机断层扫描标准，胸膜积脓可以很容易地与周围型肺脓肿区分开来。
