Spaces containing air were thus excluded. The interlobular septa (singular: interlobular septum) are located between the secondary pulmonary lobules and are continuous with both the subpleural interstitium (peripheral connective tissue) and the peribronchovascular interstitium (axial connective tissue) as well as the more delicate intralobular septa.. 7 The presence of reticulation is indicative of interstitial lung disease. The pulmonary lobule is the smallest anatomic unit of the lung surrounded by a connective tissue septum, and in some ways the lobule resembles a lung in miniature 20 ().Within the interlobular septa lie lymphatic channels and venules ().Abnormal thickening of the septa between the lobules is responsible for the short … interlobular septum: the connective tissue between secondary pulmonary lobules, usually containing a vein and lymphatics; seen radiographically when thickened as a Kerley B or septal line.
