Fig. 64. Blastomycosis affecting the lungs and bones. In A, the right side of the dia- 

 phragm is in the usual position. The costophrenic angle is clear. On the left, the diaphragm is 

 indistinctly seen; the costophrenic angle appears shallow, and there is evidence of slight 

 pleural thickening. The upper three-fourths of the right lung field shows a definite increased 

 density with multiple interspersed translucent anas. A similar picture is seen in the upper 

 portion of the left lung field. Extending outward from the cardiac shadow in the lower left 

 lung field there is density of a sott character, poorly defined and irregularly mottled. B, large 

 saucerized defects of the left fibula with periosteal reaction. Similar destructive defects are 

 seen in the upper shaft of the tibia. C, higher magnification of B. D, left elbow involvement 

 with cortical erosion of the medial epicondyle. E, similar destructive changes in the tarsal 

 na\ icular bone and in the os calcis.
