The paint brush borders sign may be seen on MRI of a giant cell tumor, at the margin between the lesion and the normal bone. The sign specifically refers to the jagged interface as the tumor penetrates into the bone which mimics the profile of the bristles of a paint brush.
It has recently been shown to be a risk factor for local recurrence of giant cell tumor.
