Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There is a nodular opacity projecting adjacent to an EKG lead in the left upper lobe . The lungs appear otherwise clear . There is no pleural effusion or pneumothorax . Mild leftward convex curvature centered along the mid thoracic spine with mild to moderate rightward convex curvature centered at the thoracolumbar junction including apparent mild loss and a lumbar vertebral body . The latter appearance , however , is probably unchanged since the prior lumbar spine radiographs .
    OUTPUT:
    
1 . No evidence of acute disease . 2 . Apparent nodular opacity projecting near the site of an EKG lead at the left lung apex . Differential considerations include a lung nodule including the possibility of malignancy although atelectasis , scarring or artifact could also be considered . Initial re-evaluation is recommended with PA and lateral radiographs in the short term when clinically appropriate . If the density were to persist , then chest CT may be appropriate to evaluate further . Findings and recommendations posted to the ER dashboard while the patient was still in the ER .
