April Fools'

Last revised by Andrew Dixon on 3 Mar 2025

The Radiopaedia editors have had a recurring commitment to prank the collective radiology community each year on April 1, an informal holiday known as April Fools' day. Sometimes months in the planning and creation, the pseudo-pathologies depicted on imaging are an exciting annual project the editors look forward to with mischievous childish delight. Each case is shared across our social media network and the growth in page visits each year is largely a reflection of our growing social media influence. However, with the increase in disinformation on the internet, this has been discontinued as not to contribute further to this problem despite the lighthearted nature.
