Correct!
2. Frontal chest radiography shows the “dense hilum” sign
The frontal chest radiograph shows a relatively dense appearing right hilum compared to the left hilum.
Figure 3. Frontal (A) and lateral (B) chest radiography at presentation shows a “dense hilum” on the right side (arrow)- note how the right hilum appears somewhat “dense” compared to the left hilum on the frontal projection (A). This finding results from abnormal opacity residing within, or overlying, the right hilum. The lateral projection (B) shows an oblong opacity (arrowhead) in the anterior segment of the right upper lobe; this opacity residents at the level of the right hilum (curved arrow) and is responsible for producing the “dense hilum” appearance on the frontal projection.
Which of the following is the most appropriate course of action to address the abnormal findings at chest radiography. (Click on the correct answer to be directed to the third of 12 pages)
