Hours to months: Pleural effusions can develop in hours to days depending on the cause. Things like heart failure, pneumonia, trauma,and abdominal issues can cause effusions to form rapidly. Plaques are usually a sign of more prolonged localized inflammation that take weeks to months or longer to develop. Hope this helps!
