They call it the face of testicular pain.

Doctors Gregory Roberts and Naji Touma at Queen's University in Kingston, Ont., have spotted what looks like the face of a screaming man in an ultrasound of a testicular tumour.

The startling image jumped out at them while scrolling through scans of a 45-year-old patient suffering from severe testicular pain.

The picture went viral after it was published in the journal Urology and it's been compared to sightings of the Virgin Mary on toast or grilled cheese sandwiches.

In the journal, the doctors say they debated "whether the image could have been a sign from a deity" -- notably the Egyptian god of virility -- but quickly dismiss it as a coincidence.

In the end, the patient decided to have the testicle removed and the tumour turned out to be benign.
