Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Multifocal areas of consolidation rapidly progressed between ___ and ___ , with the appearance on CT of ___ , attributed to a multifocal pneumonia . When comparing the scout image from the recent CT as a surrogate for a chest radiograph at that time point , the main radiographic change is development of increasing volume loss in the right upper lobe , manifested by elevation of the minor fissure . The right upper lobe remains densely consolidated , particularly centrally , and has more hazy ground - glass and in the periphery . An area of combined consolidation and ground - glass in the periphery of the left upper lobe is similar to slightly improved , and a predominant ground - glass opacity within the right lung base is unchanged . A new area of patchy and linear opacity has developed in the left lower lobe and may reflect additional site of infection . Poorly defined opacities in the juxtahilar regions are unchanged . Bilateral pleural effusions are small and similar to the recent CT . Fullness of the hilar and right paratracheal contours likely reflects reactive lymphadenopathy .
    OUTPUT:
    
Persistent multifocal consolidation and ground glass opacities , most severe in the right upper lobe . Worsening right upper lobe volume loss , but no evidence of obstructing central lesion on recent CT . Considering infectious symptoms and the rapid progression between ___ and ___ , a multilobar pneumonia is considered most likely . Differential diagnosis includes cryptogenic organizing pneumonia , eosinophilic pneumonia , and pulmonary hemorrhage / vasculitis .
