Volume loss and a veiled like appearance of the left hemithorax.
Left hilar mass.
Right lung clear.
Classical appearance and presentation of a left upper lobe collapse.
The lobe collapsed anteriorly giving a 'veiled like' appearance to the hemithorax and often as in this case discernable volume loss.
In a smoker, the cause is considered lung cancer until proven otherwise. It may be apparent on the chest x-ray as in this case with a central obstructing hilar mass. In other cases CT chest or bronchoscopy reveal a endobronchial mass.
Other less common causes include mucus plugging.
