1. What is an incomplete interlobular fissure?
The interlobular fissure divides the lung into lobes by the visceral pleural fold. These are also important anatomical landmarks on chest radiographs and chest CT scans. Therefore, it is necessary to know the anatomy of the interlobar fissures to recognize the radiographic images and assess the extent of the disease.In the case of an incomplete interlobular fissure on straight radiographs, a curvilinear, radiolucent border is medial and opacified lateral, running along the superior segment of the lower lobe. The external cause of opacity is thought to be extrapleural fat, however, pleural thickening or fluid may cause similar or more extensive imaging.

2. Causes of incomplete interlobular fissure
There are several clinical relationships of incomplete interlobular fissures such as:Adjacent lung parenchyma is fused causing disease to spread and air migration to the other side. Due to pathological processes such as pneumonia, lobar pneumonia affects the adjacent lobes through the foramen of Kohn and Lambert's duct, and causes lobar bronchial obstruction. Air migration can cause lobe air to continue when there is an obstructed bronchus through the unobstructed lobe.
