3. Organizing pneumonia secondary to UC

The patient rapidly improved both clinically and radiologically over the next 5 days (Figure 5).

Figure 5. Chest X-ray after 3 days (A) and 5 days (B) and improvement in the thoracic CT scan (C) after the increase in corticosteroids. (To view Figure 5 in a separate, enlarged window click here).

The absence of any pathogens on bronchoscopy and the rapid response to corticosteroid therapy suggested either organizing pneumonia or possibly eosinophilic pneumonia, although the BAL did not demonstrate the presence of eosinophils excluding that diagnosis.

Which of the following statement(s) regarding UC associated lung disease is/are true? (Click on the correct answer to be directed to the sixth and final page)

1. UC can be associated with airway disease including bronchitis, bronchiolitis and bronchiectasis.
2. UC lung disease is rare.
3. Parenchymal lung disease due to medication-induced lung toxicity in UC is very rare.
4. Lung disease is virtually excluded in patients with well-controlled UC.
5. UC lung disease usually does not respond well to corticosteroids often necessitating other anti-inflammatories.
