<num>. interval placement of tube at right lung base, with improvement of the right base and right medial apex pneumothorax. the degree of tension and an depression of the right hemidiaphragm and right ward shift of the mediastinum appear improved. (please note that the initial wet read suggested that the right pneumothorax was unchanged.) <num>. density at the right lung base likely reflects severe compressive atelectasis --<unk> to this area on followup films is requested. <num>. left lower lobe collapse and/or consolidation and small left effusion, grossly unchanged. <num>. cardiomegaly and mild vascular plethora, without overt chf, similar to prior.
