Right lower lobe atelectasis
Chest x-rays of a 70-year old male who fell from the stairs and has severe pain on the right flank.
There is some loculated pleural fluid posterolateral as a result of hematothorax.
Notice the abnormal right border of the heart.
The right interlobar artery is not visible, because it is not surrounded by aerated lung but by the collapsed lower lobe, which is adjacent to the right atrium. #Clinical #Radiology #CXR #Lateral #RLL #Lobar #Collapse #RadiologyAssistant
