There are diffuse bilateral interstitial and alveolar opacities consistent with chronic obstructive lung disease and bullous emphysema. There are irregular opacities in the left lung apex, that could represent a cavitary lesion in the left lung apex.There are streaky opacities in the right upper lobe, XXXX scarring. The cardiomediastinal silhouette is normal in size and contour. There is no pneumothorax or large pleural effusion.

Bullous emphysema and interstitial fibrosis. 2. Probably scarring in the left apex, although difficult to exclude a cavitary lesion. 3. Opacities in the bilateral upper lobes could represent scarring, however the absence of comparison exam, recommend short interval followup radiograph or CT thorax to document resolution.
In which body region is/are the lymph node (s) located? choose just one of the following options from this Python set:
( "trachea, carina", "unspecified", "paratracheal").
 You just have to answer with the correct option. If you can´t find any corresponding body region, then answer with the option 'unspecified'.
 In your entire response, the letter h should appear at most once.
