Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable AP radiograph of the chest once again demonstrates a stable small right pleural effusion and a chest tube in place . Although no pleural line is seen , the pulmonary vascular markings at the right apex are not as clearly visible on this study , raising concern for a small right apical pneumothorax . There is no effusion or pneumothorax on the left . There is right basilar atelectasis , but the lungs are otherwise clear . The hilar and cardiomediastinal contours are normal . There is no pulmonary edema .
    OUTPUT:
    
1 . Equivocal small right apical pneumothorax for which PA and lateral radiograph would normally be recommended ; however , the patient is on wall suction and can not be transported at this time . Continued close followup is recommended . 2 . The small right pleural effusion is unchanged .
