There is extensive patchy bilateral consolidation.
Left posterior pleural collection (3.5 x 6.9 x 4.2 cm) is noted, with an enhancing pleural rim.
Anteriorly loculated pleural fluid is also seen anteromedial to the left upper zone, abutting the mediastinum.
Multiple enlarged mediastinal lymph nodes are unchanged from 16/09/2015.
Imaged upper abdominal organs are unremarkable.
No suspicious osseous lesion.
Conclusion:
Patchy bilateral consolidation, most likely infective in nature.
Rim-enhancing left pleural collection with loculated left upper zone pleural fluid suspicious for empyema in this clinical setting, although it is possible that the pleural enhancement and loculation could also be secondary to recent VATS. Further clarification with FNA recommended.
