    INPUT: Frontal and lateral chest radiographs were obtained . The patient is status post extubation . A right IJ terminates in the lower SVC . An NG tube terminates in the body of the stomach with the sidehole at the gastroesophageal junction . A left - sided abdominal drain is present . The right upper lobe atelectasis is improved . Persistent left lower lobe opacity is present , with a small left pleural effusion . The heart size is top normal . Mediastinal and hilar contours are stable . There is no pneumothorax .
    OUTPUT:
    
1 . Persistent left lower lobe opacity , likely secondary to left lower lobe collapse but a developing consolidation can not be excluded as there is no prominent mediastinal shift . Small left pleural effusion . 2 . NG tube with sidehole at the GE junction , and may be advanced by 3 - 4 cm .
