Sagittal T1-weighted MR image (a) of the thoracic spine illustrates diffuse marrow hypointensity, which is slightly hypointense relative to the discs. Given the diffuse marrow involvement, it may be difficult to discern this marrow abnormality. Gadolinium-enhanced T1-weighted MR image (b) depicts multiple heterogeneously enhancing lesions (yellow arrows). The STIR MR image (c) shows abnormally increased signal in the posterior elements and the vertebral bodies. A compression fracture is seen in the upper thoracic spine (red arrow).
