The “Cone-Head” sign: Magnetic resonance image findings of the “Headspin Hole”, an overuse injury found in breakdancers

Breakdancing can cause the formation of a painless lump on the scalp at the vertex of the skull, with associated hair loss called a “Headspin Hole.” This occurs secondary to chronic inflammation from performing spinning dance moves on the head. We present the radiological findings of the “Headspin Hole” in a 38-year-old male with a history of breakdancing. Magnetic resonance imaging revealed a cone-shaped deformity on the vertex of the skull with deep scalp thickening adjacent to the outer-table cortex. Currently in the literature, there is no description of the radiological findings of this cone-shaped deformity on the vertex of the skull, we refer to this as the “Cone-Head Sign.”
