Fig. 58. Actinomycosis of the chest as shown by roentgenograms. A, infiltration in right 

 lower lobe with associated pleural effusion; generalized cardiac enlargement. In the lateral 

 view, the patchy infiltration was seen to occupy the right middle and lower lobes. B, sym- 

 metrical thorax with smooth high diaphragm on the right. The diaphragm on the left is in 

 average position but shows tenting. Both costophrenic angles are clear. Size and shape ol 

 heart shadow are not unusual. The right lower lobe is reduced in volume and the lung mark- 

 ings are prominent in this region. The dense shadow in the hilar region is probably due to an 

 enlarged Lymph node. In the third left interspace, a uniform density is noted which gradually 

 fades out toward the second anterior interspace. The first interspace is entirely clear. There is 

 a veil-like density throughout the lower left lung field. In the lateral film, a dense round 

 shadow, probably an enlarged lymph node, was seen in the hilar region.
