MRI shows diffusely hypointense T1 vertebrae with multiple vertebral fractures. At some levels, there is retropulsion of the fractures which compresses the thecal sac, without significant spinal stenosis or radicular compression.
There is hepatomegaly (>15 cm cephalocaudal) and splenomegaly (>13 cm cephalocaudal). No lymphadenopathy, however.
