Interstitial Lung Disease Series-Part 1- Usual Interstitial pneumonia

ILD is one of the most difficult topics for the residents to understand. We have put together simple series with points to remember for each type. We agree, it is highly controversial and our points are comprehensive and may need revision periodically.  All we are offering are some typical things to remeber and pictures and this in no way is exhaustive and conclusive .
