The lesion was surrounded by an area of hyperlucent lung parenchyma and communicated with a segmental bronchus (Figure 1).
Bronchoscopic image: the two subsegmental bronchi of the anterior bronchus of the right upper lobe can be seen. A small orifice at the upper wall of the anterior segmental bronchus is visible (arrow), which might correspond to the atretic apical segment.

A very small orifice at the beginning of the anterior segmental bronchus perhaps corresponded to the "atretic" apical segment (Figure 2).
