Lung hernia is an abnormal protrusion of the lung beyond the confines of the thoracic cage. Hernias are classified as cervical, intercostal, or diaphragmatic. Each of these types can be either congenital or acquired. Acquired hernias can be spontaneous, posttraumatic, or pathologic as a result of a neoplastic or inflammatory process. This report describes five cases of lung hernias. Two were congenital cervical hernias, detected as incidental findings on chest radiographs of infants. One was a posttraumatic intercostal hernia detected on a chest radiograph and confirmed with CT. The remaining two were acquired intercostal hernias at the site of prior chest-tube drainage of tuberculous empyemas. Although both of these were clearly shown on CT scans, only one was visible on chest radiographs.
肺疝是指肺组织突出于胸廓范围之外的异常情况。肺疝可分为颈部、肋间或膈肌型。每种类型都可分为先天性或后天性。后天性肺疝可以是自发性的、创伤后形成的，或者是由肿瘤或炎症过程导致的病理性肺疝。本报告描述了5例肺疝病例。其中2例为先天性颈部肺疝，是在婴儿胸部X线片检查时偶然发现的。1例为创伤后肋间肺疝，最初在胸部X线片上发现，并经CT证实。其余2例为后天性肋间肺疝，发生于既往结核性脓胸行胸腔闭式引流的部位。尽管这2例在CT扫描上均清晰可见，但胸部X线片仅显示其中1例。
