Abstract:
Objective: To distinguish malignant from osteoporotic acute vertebral collapses at the single location. Methods Fifteen osteoporotic and sixteen malignant vertebral collapses were studied in thirty - one patients with T1 WI, gadolinium enhanced T1 WI and T2 WI MRI. All the patients had the follow - up periods of 3 - 6 months or pathologic results from biopsy. Results Seven findings were suggestive of osteoporotic: 1. The compression of vertebral body was severe. 2. The lesion extended to the whole vertebral body was uncommon. 3. The location of the lesion was closed to the end plate of the vertebral body and the anterior and /or posterior of the vertebra was straight or concave. The posterior bone fragment can be seen. 4. Pedicles were normal. 5. No epidural soft tissue mass. 6. The vertebral vein was normal. 7. The bandilike or flakelike enhancement under the end plate. Another seven findings were suggestive of malignancy: 1. The compression of vertebral body was mild. 2. The lesion extended to the whole vertebral body was common. 3. The anterior and /or posterior of the vertebra cortex was convex. 4. Pedicles were involoved. 5:Epidural soft tissue mass was usually seen. 6. The vertebral vein was involved and disappeared. 7. The lesion was usually nodulus enhancement. Conclusion To distinguish malignant from osteoporotic acute vertebral collapses,the MRI findings of the morphology and the shape of the lesion postcontrast are useful in the differentiation of solitary acute vertebral collapses.
