What Does Posterior Margin Of D11-D12 Bulges Centrally Means?

I had a MRI done and it showed posterior margin of D11-D12 bulges centrally and projects into the spinal canal. I also have two adjacent areas of CSF signal measuring 4 mm in diameter transversely and 1 cm craniocaudal combined dimension. Can you tell me what this means? I have been referred to a neurosurgeon, but have yet to hear from them. Thank you.
