Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided AICD is stable in position . There are low lung volumes . Prominence of the central pulmonary vasculature likely accentuated by low lung volumes and AP technique . Patchy right basilar opacity may be due to combination of vascular structures and low lung volumes but a consolidation is not excluded in the appropriate clinical setting . No large pleural effusion or pneumothorax . Calcified ventricular aneurysm is again seen . Cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
Low lung volumes which accentuate the bronchovascular markings . However , consolidation is not excluded at the right lung base .
