To the Editor:

I read with interest the review on adult congenital central airway anomalies by Mehta and colleagues1 in an issue of CHEST (July 2015). The authors describe trifurcation of the left main bronchus comprising the left upper lobe (LUL), and lingular and left lower lobe bronchi, as depicted in Figure 5B in their article.1

From the anatomic perspective, a normal LUL bronchus divides into an upper division bronchus and lingular bronchus.2 Lung parenchyma supplied by the lobar bronchus has its complete overlying pleura. Is the LUL bronchus in Figure 5B of the article by Mehta et al1 a true lobar bronchus or, in fact, the upper division of the LUL bronchus—a sublobar bronchus? The discrimination is important because accurate and precise airway terminology is essential for communication between bronchoscopists.
