The features of interlobar (intrafissural) pneumothorax are little known. Of the 4 cases reported here, 1 was associated with spontaneous pneumomediastinum and 3 were consecutive to pleurodesis for spontaneous pneumothorax. Interlobar pneumothorax does not occur unless pleural adhesion is present. The diagnosis is confirmed by radiography of the chest which shows an oblong air-clear area prolonged by a fissural line and corresponding, on lateral projection, to the normal fissure. This image should not be confused with that of pneumatocele, which also resolves spontaneously.
叶间（裂内）气胸的特征鲜为人知。在此报告的4例中，1例与自发性纵隔气肿相关，3例继发于自发性气胸的胸膜固定术。除非存在胸膜粘连，否则不会发生叶间气胸。胸部X线检查可确诊，其显示一个椭圆形的透亮区，由一条裂线延长，在侧位投影上与正常裂相对应。此影像不应与同样可自发消散的肺气囊影像相混淆。
