Ask a Doctor and Get an Answer to Your Medical Question ASAP
Good morning, I am Dr Ruff, thank you for contacting us today.
What is your question please?
Also what symptoms have you had to require an MRI please?
Okay thanks you. So reduced signal of marrow can imply it is being replaced by something else such as fatty tissue. This can be as a consequence of injury to the spine, but also due to some problems with the marrow itself.
It is certainly quite non specific, but haematology are your best option as they may consider taking a small sample of it to assess it.
It is possible that a small infarct can cause this. It is also possible with migraines to have these small infarcts as well which can been seen in younger people.
I think excluding Myeloma is reasonable given what has been seen, but it doesn't really bring all of these symptoms together. Therefore makes my think it could be an incidental finding within the spine of no concern.
