Diffuse abnormal marrow signal in a malignant VCF. Sagittal T1WI of the lumbar spine demonstrates a malignant VCF of L2 with marked complete replacement of the normal high T1 vertebral body marrow signal. The diffuse T1 hypointensity indicates tumor infiltration. Note the convex, expanded border of the posterior vertebral body versus the normal posterior concavity of the adjacent vertebral bodies.
