5
Q
What are some of the features of interstitial lung disease?

8
Q
What is the differential diagnosis for honeycombing of the lungs?
A
- Scleroderma: Presents with honeycombing in bases of lungs.
- Eosinophilic granuloma: Honeycombing in the upper lung fields.
- End stage interstitial disease
9
Q
What is the difference between alveolar and interstitial patterns?
A
Alveolar - diffuse white out of the lungs
Interstitial - dirty lungs (lines, military nodules, honey combing)
