| This exercise is intended for Pulmonary fellows and radiology Residents. Try your skills in evaluating cavities in chest x-ray. First identify the characteristics of the cavity. Generate a list of differential in your mind. Without knowing the clinical information, a specific diagnosis is difficult to make. Click on labeled image to see what the case turned out to be. If it was in your differential you should be happy. If you cannot find the answers for the questions raised, contact me. | ||
| Case 1 | Labeled Image | What are the conditions where you get thin walled cavities? |
| Case 2 | Labeled Image | What is the differential for multiple cavities? |
| Case 3 | Labeled Image | What is the differential for thick walled cavity? |
| Case 4 | Labeled Image | What are the contents of a cavity? |
| Case 5 | Labeled Image | How do you distinguish septic emboli from aspiration pneumonia? |
| Case 6 | Labeled Image | What is the differential for air fluid levels in the mediastinum? |
| Case 7 | Labeled Image | What is the etiology for lung abscess in the anterior segments? |
| Labeled Image | I treated this patient as having
lung abscess secondary to aspirated coin. The cavity turned out to be due
lung cancer.
Moral: Close follow up until the problem is resolved. |
