Blade of grass sign

Dr Tim Luijkx and almehdi et al.

The blade of grass sign (also called the candle flame sign) refers to the lucent leading edge in a long bone seen during the lytic phase of Paget disease of bone

The blade of grass sign is characteristic of Paget disease of bone. This is akin to osteoporosis circumscripta cranii seen in the skull.
