1A: Campanacci grade 1 lesion: Bone contour maintained, purely intra-osseous lesion. Thinning of cortex may be seen 1B: X-ray (antero-posterior) of wrist showing Campanacci grade 2 lesion: Cortical expansion with thin bony rim; but no breach 1C: X-ray (antero-posterior) of wrist showing Campanacci grade 3 lesion: Deformed contour, cortical breach with soft tissue extension
