Large well-defined presacral mass showing heterogeneous signal intensities on both T1WI and T2WI. The signal intensities of this mass are similar to signal intensities of bone marrow in adjacent vertebrae. Minimal post-contrast enhancement.
The vertebrae have coarse trabeculation and heterogeneous signal intensities, as do the pelvic bones included in the study.
Desiccation of the lower lumbar intervertebral discs. No disc bulge or herniation.
