Chest

ct

Right pigtail drain in situ with tip within the right mid-posterior hemithorax. Moderate sized loculated right pleural fluid with thin surrounding rim of enhancement. There are a couple of locules of gas within the collection, likely related to drain insertion (inserted today).

There is a cavitating focus in the left upper lobe anteriorly with irregular thick margins, spiculations, and linear bands extending to the pleura. The cavity communicates with a bronchus. The lesion measures approximately 25 x 25 x 25 mm (excluding linear bands). No evidence of surrounding inflammation or fluid within the cavity.

6 mm subpleural nodule in the left anterior upper lobe.

Mild emphysematous change in the lung apices.

No size significant mediastinal or hilar lymphadenopathy by CT size criteria. Right paratracheal node measuring 10 mm in short axis.

Chest

x-ray

Post-VATS imaging showing residual basal atelectasis and intercostal drain on the right.

Case Discussion

Although a drain has been inserted at the admission with drainage of frank pus, the cardiothoracic surgeon was consulted and the patient was offered VATS decortication.
