Radiograph Classification

Subset 3

Radiograph #36

Answer Key #36 pdf icon[PDF – 493 KB]

Bilateral chest wall plaques are present. Note the sparing of the apices and costophrenic sulci. In profile plaque is noted on the right with calcification. Face on plaque is noted bilaterally with calcification. All other boxes under site and calcification are recorded as 0. Extent for both R and L is 3; and width is c on the right.

Radiograph #37

Answer Key #37 pdf icon[PDF – 493 KB]

No small pneumoconiotic opacities are seen, but definite pleural thickening is present. The plaques on the left spare the costophrenic sulcus and apex (review Subset 1). Face-on and in-profile chest wall plaques with calcification on the left, bilateral calcified diaphragmatic plaque, and paraspinal calcifications (“other sites”) should be recorded in Section 3B. Note that the diffuse pleural thickening on the right involves the costophrenic sulcus and extends up the chest wall; it should be recorded in 3C. The extent is 1 and the width is a, noting the presence of calcification.

Radiograph #38

Answer Key #38 pdf icon[PDF – 493 KB]

Note the extensive, calcified, in-profile and face-on left chest wall plaques that spare the apex and costophrenic angle. There is obliteration of the right costophrenic angle with diffuse pleural thickening. There are no small pneumoconiotic opacities.
