Learning objectives

To see beyond anatomical structures and diagnostic radiology in our daily practice. Let your imagination fly and enjoy an alternative view of common images.

Background

Pareidolia is the tendency to interpret a vague stimulus as something known to the observer, such as seeing shapes in clouds or seeing faces in inanimate objects or abstract patterns [1].

Findings and procedure details

We present a selection of radiological pareidolias we have encountered on images from our institution. We have also regularly shared these, as well as other pareidolias, on our social media channels [6-7]. Open your eyes... Can you see beyond echogenicity, opacity, density and, signal intensity? Let's start!

Conclusion

Radiology has an alternative interpretation that can add an amusing touch to our daily practice.
