Three cases of benign giant cell tumor with unusual imaging features.

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.
