Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is normal . The hilar mediastinal contours are normal . Focal consolidation projects over the posterior costophrenic angles on the lateral view , potentially localizing to the right on the frontal . There is no pleural effusion or pneumothorax . Note is made of a possible right shoulder deformity , overall unchanged compared to the prior exam .
    OUTPUT:
    
Focal opacity at the posterior costophrenic angle on the lateral view , not clearly localized on the frontal view . This could be infection in the proper clinical setting in which case repeat after treatment is suggested . In the absence of supportive symptoms however a CT scan should be performed - non necessarily in the acute setting . No visualized acute fracture however if desired , dedicated rib series could be performed .
