Immune checkpoint inhibitor-related chronic pneumonitis: a case report and literature review.

Immune checkpoint inhibitors (ICIs) are a type of medicine that helps fight stomach cancer but sometimes they can cause problems with the lungs. This case report is about a man who had two bad lung incidents after taking ICI medicine. He had trouble breathing and fever both times. Other people have had similar problems with their lungs after being given ICI treatment. We compared chest pictures of the patient receiving ICI treatment over time and saw changes in the same spot meaning there might be a long-term problem with the lungs. We need to do more research to figure out how to treat this problem better.
