Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A tracheostomy catheter appears in standard unchanged position . A catheter overlying the right mid clavicular line appears similar to prior examination , possibly a VP shunt . Elevation of the right hemidiaphragm is unchanged from prior . Linear bibasilar opacities are unchanged and likely reflect atelectasis . No confluent consolidation is identified . A significant widening of the right paratracheal stripe corresponds with a known large thyroid goiter , better characterized on prior chest CT . Leftward tracheal deviation appears stable . The remainder of the mediastinal and hilar contours are within normal limits for age . The heart size is borderline or slightly enlarged . There is pneumothorax .
    OUTPUT:
    
1 . Grossly stable thyroid goiter causing widening of the right paratracheal stripe . 2 . Unchanged elevation of the right hemidiaphragm and bibasilar atelectasis . 3 . No evidence of pneumonia or acute pulmonary edema .
