Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: As previously noted , there is left hemithorax volume loss due to prior left lower lobectomy . A consolidative and fibrotic process with associated fiducial markers remains in place laterally in the left upper lung zone . This is stable compared to multiple prior exams . While there is a mild accentuation of the interstitial markings , no focal consolidation or superimposed edema is noted . Mild aortic tortuosity with calcified plaque at the arch is again noted . The cardiac silhouette remains enlarged but stable . No definite effusion or pneumothorax is noted . Degenerative changes are noted throughout the thoracic spine and in bilateral shoulders . No displaced rib fractures are evident . There are no suspicious lucent lesions .
    OUTPUT:
    
Overall stable chest x-ray examination with slight diminished lung volumes resulting in bronchovascular crowding . There may be mild edema ; however , no frank failure is identified .
