Hi Becka

It is a difficult and worrying time for you and I understand your concerns which are quite valid. Getting it diagnosed may not be that straight forward so further imaging with a bone scan and CT may shed more light on the diagnosis. I really am not an expert on the diagnosis - it really is the ortho's job. Perhaps the Dr just isn't that sure yet, or maybe he just wants to confirm his diagnosis before giving you all the facts.

I presume from the Wikipedia reference-linkMRI that they can get a look at the architecture of the lesion and gives some likelihood whether or not it is a cyst. I understand that cysts are often quite distinctive. The CT may be another way of getting the image. The bone scan looks at uptake of a radioactive marker. The greater the uptake indicates an area of higher metabolism - as you might see with a bone cancer or an inflammatory process. So the bone scan may be used just to rule out the chance of something more sinister like cancer. There could be other reasons for the tests that I am not aware of. Presumably you have or will also have other things such as blood tests.

It could be he just isn't that sure yet. Are you going to have the imaging done soon? If you mean this Monday then you might as well wait till the results are in. However if you are having to wait then I would get in contact. You have a right to know as much as can be known at this stage.

It is good you have gotten onto it. It is always better to know.
