BMJ case report: Man developed a 'headspin hole' after years of breakdancing

[Still Waters]

Breakdancing’s extreme physical demands mean it is known to involve a high risk of injury: everything from hair loss to sprains and damage to almost every part of the anatomy.

But now breakdancing enthusiasts have been warned of a new danger: that spinning on their heads too much could lead to them developing a sizeable protrusion on top of their head.

This has emerged as a potential hazard in a case report in a leading medical journal about a man in his 30s in Denmark who developed such a visible lump on his head, as a result of undertaking breakdancing training up to five times a week for 19 years, that he had surgery to remove it.
