There is now interval development of mild pulmonary vascular congestion with a new vague opacity in the periphery of the mild right mid lung field . Bibasilar airspace opacities persist , likely reflecting worsening atelectasis . There is no pneumothorax . No large pleural effusion is demonstrated .
