Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison with prior radiographs , again seen is near complete opacification of the left hemithorax owing to lower lobectomy and total collapse of the residual upper lobe as well as leftward mediastinal shift . The right lung however shows increased vascular congestion and interstitial thickening as well as a probable small pleural effusion . Lucency projecting over the mid chest , best seen on the latera view , is of unclear etiology , but could related to dilated , air filled esophagus . Minimal fibrotic changes are unchanged . Lumbar spine hardware is redemonstrated . Stable severe compression of a lower thoracic vertebra .
    OUTPUT:

Again seen near complete opacification of the left hemi thorax with complete collapse of the residual left upper lobe and lefward mediastinal shift . Lucency projecting over the mid chest , best seen on the latera view , is of unclear etiology , may have been present previosuly and possibly related to dilated , air filled esophagus .
