Correct!
5. The thoracic CT shows that the nodule is partially calcified but also reveals a left mainstem bronchial lesion
The thoracic CT confirms the nodule resides in the subpleural region of the right upper lobe and is partially calcified (Figure 4).
Figure 4. The peripheral right lung nodule (arrows) is circumscribed and partially calcified, which suggests a benign etiology. However, the thoracic CT also shows a polypoid, lobulated lesion (arrowheads) arising from the medial aspect of the left mainstem bronchus.
There is no evidence of low attenuation within the nodule to indicate fat to suggest the diagnosis of hamartoma. There is no evidence of bronchiectasis or fibrotic lung disease. The thoracic CT does also show a polypoid lesion residing within the left mainstem bronchus (Figure 4, arrowheads).
