There is central mass seen the left hilar region measuring encasing the
distal part left pulmonary artery and narrowing it as well as superior pulmonary vein and occluding the left upper bronchus with a secondary total collapse of the left upper lobe.
There are multiple enlarged mediastinal lymph nodes are seen, the largest one is perivascular.
A tiny right hilar lymph node is seen. No evidence of axillary lymph nodes on both sides.
Apart from the evidence of mild emphysematous lung changes seen in the right lung, there is no convincing pulmonary lesion seen within.
No evidence of pleural or pericardial effusions.
The liver is average size with a few tiny focal lesions in segments VII and VIII the largest one is subcapsular too tiny to characterise, for follow-up. No intrahepatic biliary radical dilatation. Patent and not dilated portal vein.
The case represents a newly diagnosed non-small cell lung cancer (squamous cell carcinoma) by bronchoscopy and requested for baseline CT study, and showing above-mentioned finding of left upper lobe lung collapse due to cancer bronchus and the case also demonstrates luftsichel sign due to the hyperexpanded superior segment of the left lower lobe, which insinuates itself between the left upper lobe and the superior mediastinum, sharply silhouetting the aortic arch and resulting in a lucency medially.
