ABSTRACT

Total left upper lobe atelectasis is caused by obstruction of the left upper lobe bronchus. This may be due to pulmonary mass, mucous plugging or foreign bodies. In older individuals, a pulmonary mass is a common cause. PA films of left upper lobe atelectasis demonstrate opacification of the left upper lung field with obliteration of the left cardiac border. In addition, there is often a relative lucency adjacent to the aortic knob which represents an overinflated lower lobe. This lucency is referred to as the Luftsichel sign. The lateral film demonstrates anterior displacement of the major fissure with increased anterior opacification. This patient had a previously known left upper lobe mass with total left upper lobe atelectasis proven by CT scan.

No MeSH data available.


Because of the volume loss from the LUL collapse, there is elevation of the left hemidiaphragm (green arrowheads).
