    INPUT: Heart size , mediastinal and hilar contours are normal . 2 .1 x 2 cm diameter poorly defined nodule in periphery of the right upper lobe is associated with a pleural tag extending to the lateral pleural surface . Multifocal bronchial wall thickening is present , particularly in the right perihilar region , but also within the infrahilar area on the lateral view . Poorly defined opacities are present in the left retrocardiac region , and note is made of a small left pleural effusion . Trace amount of fluid is also demonstrated within the fissures on the right . Bones are diffusely demineralized , and note is made of a moderate compression deformity at approximately the T10 vertebral body level .
    OUTPUT:
    
1 . Multifocal bronchial wall thickening and patchy left lower lobe opacities , which could potentially be due to an acute infectious etiology given clinical suspicion . 2 . 2 cm peripheral right upper lobe lung nodule is concerning for a lung cancer , likely adenocarcinoma subtype . CT of the chest is suggested for further evaluation . Considering clinical suspicion for infection and other multifocal abnormalities in the chest on the current study , it may be reasonable to first complete a course of antibiotic therapy prior to CT . 3 . Small left pleural effusion . Dr . ___ was telephoned with these results at 8 : 55 a .m . on ___ at time of discovery .
