Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient has a known posterior right eighth rib fracture , not well depicted on these views . Again seen is pigtail catheter overlying the right upper lung , with platelike subsegmental atelectasis at the right base , essentially unchanged . A tiny right apical pneumothorax appears to be present , very slightly larger than on the prior study . Otherwise , I doubt significant interval change . Subsegmental atelectasis at the left base is again also noted .
    OUTPUT:
    
Right upper zone pigtail catheter in place , with subsegmental atelectasis the right lung base , similar to prior . There is a tiny right apical pneumothorax , very slightly larger than on the prior study .
