Spinal metastasis-MRI

This is MRI lumbar spine of a 70 yr old male who came to us with complaints of back pain and pain in both lower limbs. It shows evidence of osseous destruction along with marorw signal abnormality of multifocal vertebral bodies involving all lumbar vertebral bodies, sacral ala. There is epidural soft tissue component with involvement of the posterior elements, appearing heterogeneously hyperintense on STIR and hypointense on T1W along with compromise of neural sac.
Four MR patterns of vertebral metastatic disease are seen – focal lytic, focal sclerotic, diffuse inhomogenous, diffuse homogenous. The most common among them is focal lytic lesions characterized by low signal intensity on T1 and high on T2. Pedicle destruction is more in favour of metastatic etiology. Pathologic compression fractures are also seen and show comparatively low signal intensity on T1 and high signal on T2 as compared to benign osteoporotic fractures which are mostly isointense on all sequences.
