Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is mildly enlarged . Mass - like opacity within the right middle and lower lobes as well as right hilar lymphadenopathy are re- demonstrated , and allowing for differences in technique , there appears to be more hazy opacification noted in the right lung base which could suggest postobstructive infection . Mediastinal lymphadenopathy is better demonstrated on the previous CT . There is no pulmonary vascular engorgement or new areas of focal consolidation . No pleural effusion or pneumothorax is seen . Compression deformity of a mid thoracic vertebral body is unchanged .
    OUTPUT:
    
Allowing for differences in technique , there may be slightly increased hazy opacification in the right lung base which may reflect postobstructive infection superimposed upon known malignancy involving the right middle and lower lobes . Right hilar and mediastinal lymphadenopathy redemonstrated , better depicted on prior CT .
