4. The lesion is circumscribed, arising from the left upper lobe airway
The images show a fairly well-defined, or circumscribed, lesion arising from the left upper lobe bronchus, filling and expanding the anterior segment left upper lobe bronchus. While the lesion, and associated mucus impaction, shows minimally lobulation, it is not infiltrative-appearing, nor is it overtly invading adjacent structures; rather, it appears somewhat indolent. The lesion is associated with air trapping in the left upper lobe, rather than post-obstructive consolidation- note the left upper lobe hyperlucency best seen on Figure 2B, outlined by the left major fissure posteriorly. The internal portions of the lesion, best appreciated on the soft tissue window images Figures 2I and J, show the internal aspects of the lesion to be hyperattenuating, consistent with enhancement, rather than displaying the low attenuation typical of necrosis.
Which of the following represents the most appropriate next step in management at this point?
