Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An NG type tube is present . The tip overlies the lower mediastinum , presumably in relation to the distal neo esophagus , similar to the prior film . Again seen is left - sided chest tube , with skin ___ and subcutaneous emphysema seen along the lower left chest wall . As before , tube lies along the lateral aspect of the chest wall . A tiny residual pneumothorax is likely present . Previously seen postoperative pneumoperitoneum is no longer visualized . Mild prominence the cardiomediastinal silhouette is unchanged . Upper zone redistribution an bibasilar atelectasis upper zone redistribution is similar to the prior film . Platelike atelectasis and bibasilar atelectasis is more pronounced . Patent GE retrocardiac opacity is slightly more pronounced . No gross effusion . No right - sided pneumothorax . Small ( 6 .9 mm ) , nonaggressive rounded lucency in the right proximal humeral diaphysis , with sclerotic rim , is similar to ___ .
    OUTPUT:
    
Probable tiny residual left apical pneumothorax . Increased atelectasis in the left mid zone and at both bases . Nonaggressive small rounded lucency in the right proximal humerus , unchanged compared with ___ . -- is there history of prior shoulder biceps surgery to account for this ? If not , the most likely differential diagnosis would include normal variant changes at a muscle insertion site . In the absence of local symptoms , recommend followup right shoulder radiographs in approximately 6 months to confirm expected stability .
