    INPUT: Peripheral right upper lobe lung nodule has grown compared to the prior CT chest of ___ and chest radiograph of ___ . On the prior chest radiograph , it measured 1 .6 cm in diameter and now measures 1 .9 cm . As AP technique may magnify the nodule , dedicated chest CT may be considered for more accurate assessment of interval growth as well as possible development of lymphadenopathy in the right hilum . Heart remains enlarged . Low lung volumes accentuate the pulmonary vascular structures . Minor bibasilar atelectasis is present . No definite pleural effusion . Single - lead pacer remains in place , with lead terminating in right ventricle .
    OUTPUT:
    
1 . Slowly growing peripheral right upper lobe lung nodule is concerning for primary lung adenocarcinoma . Dedicated chest CT may be considered for more accurate assessment as well as to evaluate for possible right hilar lymph node enlargement warranted clinically . 2 . Low lung volumes limit assessment of the lung bases for pneumonia . Given clinical suspicion for this entity , this could be further evaluated with repeat chest radiograph with improved inspiratory level . Dr . ___ was paged with these results at 8 : 15 a .m . on ___ , at the time of discovery .
