Objective: Imaging findings for giant cell tumors (GCT) of the spine displaying aggressive characteristics have not been widely reported.

Materials And Methods: Patients with biopsy-proven GCT were included in the study. Three cases fulfilled these criteria.

Results: MRI and CT demonstrated disc space involvement and vertebral body compression.

Conclusion: Acute fracture, subluxation, and extension through the disc space have not been previously described and, while atypical for benign lesions, may in fact be typical for GCT of the spine.
