Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Artifact from the patient 's hair overlies the right left lung apices . Inspiratory volumes are slightly low . Probable mild cardiomegaly . There is bibasilar atelectasis with small bilateral effusions . No definite consolidation or infectious infiltrate . The mid and upper zones are grossly clear , without infiltrate . The apices , as noted , are obscured by overlapping artifact . There are calcified mediastinal and hilar lymph nodes , suggesting prior granulomatous disease . At the right base laterally , there is a small focal irregularity , which may simply be artifact due to fluid and atelectasis . However a focal pulmonary nodule , possibly a calcified granuloma , might also account for this appearance . Mild degenerative changes noted in the thoracic spine .
    OUTPUT:
    
Small bilateral pleural effusions and bibasilar subsegmental atelectasis . Although an infectious infiltrate or area of aspiration pneumonitis can not be entirely excluded , the appearance is more suggestive of atelectasis . Elsewhere , no focal infiltrate or consolidation . Bilateral apices are partially obscured . Probable mild cardiomegaly . Calcified hilar and mediastinal lymph nodes , consistent with prior granulomatous disease . Small focal density at the right base laterally is partially obscured by surrounding effusion and atelectasis . Attention to this area on followup films is recommended to exclude a focal nodule or calcified granuloma .
