Is Lystic Lesions On Spine, Partial Destruction Of L5 With Large Soft Tissue Mass Serious?

hi
the conclusion of my husband's recent consult state numerous lystic lesions throughout the spine, partial destruction of the l5 with large soft tissue mass associated. involvement of multiple other vertebrae as well as posterior of right 9th rib. no abnormality in chest abdomen or pelvis. consistent with multiple myeloma or metastatic disease.

we have not yet done next phase. he has no other symtoms eg urinary etc. to indicate he is sick after from this after lifting our 9mth doctor

thanks
