MI

This is Dressler’s Syndrome or postcardiac injury syndrome which occurs weeks to months after an MI. The pathogenesis is immunologic. The sequential radiographs show a pre-op clear lung (green arrow is clear left lung base), a post-op with segmental atelectasis at the left base (yellow arrow), and a left pleural effusion a month later (red arrow). A pleural or pericardial effusion is often seen in Dressler’s syndrome. Treatment is NSAIDs.
