The findings are: - Large density on the left with loss of cardiac silhouette. - High position left diaphragm with tenting. - Low position minor fissure - Low position right hilum These findings indicate a total atelectasis of the left upper lobe and possibly also partial atelectasis on the right. Since the silhouette of the right heart border is still visible, there is probably partial atelectasis of the lower lobe and not of the middle lobe. #Clinical #Radiology #CXR #Lateral #LUL #Lobar #Collapse #Luftsichel #Sign #LuftsichelSign #RadiologyAssistant
