Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to earlier the same day , I doubt significant interval change . Again seen is a moderate to moderately large right pleural effusion . There is likely underlying collapse and / or consolidation , although the level of the diaphragm is obscured . A small amount of fluid is again seen extending into the minor fissure . Heart size is at the upper limits of normal . The cardiomediastinal silhouette remains midline . The left lung and the upper right lung remain grossly clear . No CHF or left - sided effusion . A small , somewhat rounded density is noted along the lower edge of the left anterior fourth rib adjacent to the chest wall , not fully characterized --? question due to something outside the patient . Minimal wedging of the presumptive T10 and ___ vertebral bodies , slight accentuation of kyphosis at T10 - ___ is again noted , unchanged .
    OUTPUT:
    
Moderate to moderately large right base effusion , unchanged , with underlying right base collapse and / or consolidation . The right hemidiaphragm itself is obscured . Heart size at the upper limits of normal . No CHF , left effusion , or other focal opacity . The left lung remains well expanded . Small ( approximately 8 .6 mm ) , rounded density adjacent to the left chest wall in the mid zone -- question something outside the patient . Attention to this area on followup films is requested . If clinically indicated , oblique views of the chest may help for further characterization .
