Lobulated ground glass nodule within the posterior basal segment of the right lower lobe is unchanged in size and density compared with the prior study. Normal vessels and attenuated bronchi traverse the lesion. No solid component present. Unfortunately automated segmentation for volumetric assessment was unsuccessful due to the ground glass nature of this nodule.
A few subtle areas of ill-defined, small and non-specific ground glass opacity elsewhere, tiny pulmonary nodules and atelectasis/scarring in the lingula and middle lobe are of doubtful clinical significance.
No overt lymphadenopathy.
Small volume pericardial and right pleural fluid has developed.
Conclusion: Stable well-defined right lower lobe lobulated ground glass nodule. This remains suspicious for a low grade adenomatous lesion. Further follow-up in 3-6 months suggested.
