A chest X-ray demonstrated left lobe opacities suggestive of pneumonia (Fig. 7).
CT scan showing diffuse grinding glass density in the left lung, suggesting the possibility of bleeding. The left main bronchus and its branches were not patent, thus suggesting clots or secretions caused by blockage.

The left main bronchus and its branches were not patent, possibly because of clots or secretions caused by blockage (Fig. 8).
The left bronchial artery is abnormal and uneven in thickness. A local tumor-like dilatation of the left bronchial artery can be seen on the CT scan.
