PURPOSE: This study was performed to evaluate differentiating features of spinal compression fractures between benign and metastatic lesions. MATERIALS AND METHODS: We reviewed MR imaging in 52 patients (benign 38, metastasis 14) with vertebral compression fracture. Signal intensity of fracture and uninvolved areas, presence of contrast enhancement, fragmentation, and paravertebral mass were analyzed retrospectively. RESULTS: Signal intensity of fracture site was variable in benign lesions, but low signal intensity on T1-weighted image and high on T2*-weighted image were seen in all cases of metastasis. Signal intensity of uninvolved area was high on T1-weighted image and low on T2*-weighted image in 84% of benign lesions. On the contrary, normal marrow signal intensity was not seen in the uninvolved areas of all metastatic fractures. Contrast enhancement were observed in all cases of benign & metastatic compression fractures. Fragmentation were seen in 1 case of metastasis(7%) and in 11 cases of benign lesions(29%). Paravertebral mass were seen in 5 cases of metastasis(36%) and in 7 cases of benign lesions(18%). CONCLUSION: Presence of normal marrow signal intensity in the uninvolved area of fracture site could be the most useful sign for differentiating benign causes from metastasis.
