Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to ___ chest radiograph , a cavitary lesion in the superior segment of the right lower lobe is again demonstrated with apparent decrease in size of the intraluminal nodule previously interpreted as suspicious for a mycetoma . 2 adjacent cavitary lesions in the right apex are grossly unchanged . No new or worsening lung abnormalities are detected . Eighth cardiomediastinal contours are stable . Healed bilateral rib fractures are again demonstrated .
    OUTPUT:
    
Apparent decrease in size of dependent nodular opacity within cavitary superior segment right lower lobe lesion , possibly representing a mycetoma . This finding and 2 adjacent right apical cavities are somewhat difficult to compare radiographically and CT may thus be considered if precise assessment of interval change is warranted clinically .
