Paint brush borders sign

Dr Daniel J Bell et al.

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.

Bone tumours

The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient.
