A region of what appears to be atelectasis is seen in the lingular segment of the left upper lobe. It appears smaller than the corresponding lesion seen on CT however this may be due to relatively low density of the periphery of the lesion. Comparison with previous chest x-rays would be helpful to confirm that the lesion is not smaller in size.
Elsewhere the lungs and pleural spaces are clear. The cardiomediastinal contours are normal.
