Found it on Google:
Vertebral Body Ishemia in Posterior Spinal Artery Syndrome
Spine 28 (13): E260-E264 July 1,2003
Anybody suscribe to this periodical?
The article discussed hyperintensity of bone marrow signals and had something to do with the blood supply to the vertebral body. Personally, have never encountered this but sounds interesting.

Yeah, I googled it too, but it seems that it could mean other things such as bone marrow disorders, tumours, or osteomyelitis.
In the case of this patient, the MRI (without contrast) was of the lumbar spine and was normal, but I noticed this sentence and wondered what it meant. Any other thoughts?

It could mean anything. But with every imaging scan, there should be a follow up. If the MD saw the report, it could generate other questions that may be persued by other medical diagnostics. The bone marrow is vital and anything that looks suspicious with it should be taken seriously.

Sarah, it would be great if all radiologists provided a 'mini-differential' when they make comments like that but unfortunately they don't.

An 'abnormal marrow signal' reading is not helpful other than to push for more imaging. The latest fad in radiology is to wax eloquent on the vertebral body hemangioma. We see so many hemangiomas these days that we're beginning to wonder if hemangiomas are the norm rather than the exception.

This is interesting news. I do not hear or read reports that contain the word hemanigioma in MRIs of the spine. Hope some radiologist out there is looking at this. Maybe they can come out with the study then

Also it depends where in the body you see this.
See it frequently in knee injuries, it may be analagous to a "bone bruise" or show early OA depending on the state of the overlying cartilage.
Pretty general term overall.

Greg,
Is the hemangioma something to be concerned about in the lumbar spine?

I don't think hemangiomas are really anything to be concerned about at all. Theoretically they may be a problem but usually they're found fortuitously on MRI. They're very common. See http://bonetumor.org/tumors/pages/page132.html
