Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged including borderline cardiomegaly with a left ventricular configuration as well as moderate tortuosity of the descending thoracic aorta and aortic calcification . A moderate - sized eventration is noted along the anterior right hemidiaphragm . Streaky associated opacities at the right lung base have increased somewhat , but most suggestive of atelectasis associated with the eventration . There is no definite pleural effusion or pneumothorax . A vague calcified nodular density measuring about 15 mm , projecting both over the left mid lung and course of the left posterior lateral seventh rib , appears unchanged ; given lack of change , presumably this is a benign finding . There is mild rightward convex curvature centered along the lower thoracic spine . Mild degenerative changes involvement through lower thoracic levels . The bones are probably demineralized .
    OUTPUT:
    
Streaky right basilar opacities , probably due to atelectasis , associated with an eventration of the right hemidiaphragm . Stable nodular focus projecting over the left mid lung .
