Findings

The C3-4 intervertebral space is severely narrowed. There is lysis associated with the oC3-4 end plates surrounded by sclerosis. There is mild spondylosis associated with the same intervertebral space. In the remainder of the spine, there is ventral spondylosis in the distal thoracic spine and lumbar spine. On the lateral projection of the thoracic spine the trachea is deviated dorsally and there is a diffuse interstitial pattern of the visible portions of the lung. Also on the lateral projection, a rounded opacity is observed superimposed on the dorsal aspect of the 6th ribs and is though to represent a summation artifact. On the VD projection of the thoracic spine, there is a bulge in the cardiac silhouette in the region of the left auricle and mild abaxial deviation of the mainstem bronchi.
