Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours are similar to the prior CT . New right apical opacity is more suggestive of active infection than malignancy . Areas of atelectasis in the superior segment of the right lower lobe as well as the right middle lobe appear similar to the prior examination . Vague opacity is present in the lingula , although the latter is not necessarily changed . The chest appears hyperinflated . There is no pleural effusion or pneumothorax . Two substantial mid thoracic compression deformities appear unchanged . The bones appear demineralized .
    OUTPUT:
    
Impression : New right upper lobe opacity suggesting the possibility of active infection . Post-obstructive pneumonitis could be considered in the setting of some recent concern for increasing right hilar malignancy .
