What are the MRI characteristics and clinical considerations for vertebral body neoplasms, and how can they be differentiated from other spinal pathologies?

Vertebral body neoplasms often present with isolated or noncontiguous involvement, frequently affecting the pedicles. MRI typically shows low T1 and high T2 signal intensity with restricted diffusion. The intervertebral disk is usually spared, except in cases like prostate cancer metastases. Enhancement patterns can obscure metastases within fatty marrow. Key diagnostic features include the preservation of the disk space and the presence of a soft tissue mass. Clinical pearls include considering multiple myeloma and lymphoma as potential mimickers. A common pitfall is mistaking degenerative changes for neoplastic involvement, particularly in the elderly.
