[Chest radiography based on the interlobar fissures].
Recognition of which interlobar fissure in the right lung is major or minor is important in chest radiography. Based on assessment of the interlobar fissure, the location of diseases or the degree of expansion of the lobes is comprehensible. As a general rule, the major fissure is not seen in normal cases. However, the major fissure is visualized in the presence of volume loss of the lower lobe. Although the medial end of the minor fissure is at the intermediate artery between the upper and lower lobe bronchi, that of the major fissure is continuous to the central portion of the mediastinum. The following cases will be presented: post-pleuritis, atelectasis of the superior segment of the lower lobe (S6), obstructive pneumonia in the middle and lower lobes due to stenosis of the intermediate bronchus, pneumonia of the upper lobe, and superior accessory fissure with atelectasis of the upper lobe.
