I have a question pertaining to a schwannoma surgery recovery. After a recent MRI, on the 12th axial slide of each view, a small spot is appearing inside the spinal cord. it’s whiter on T2. Could this just be scar tissue? Or is it possible that the tumor has reoccured. Thank you.
A schwannoma is typically a benign nerve sheath tumor of the schwann cell. The schwann cell is an insulating cell for the peripheral nerve and creates the myelin sheath. This tumor normally does not involve the spinal cord but in certain locations, the pressure from this tumor can cause injury to the cord.
Either by the original compression of the tumor or occasionally the surgical removal, a scar can occur on the cord that shows up as a white spot on the T2 images on the MRI. Ask your surgeon if it is a scar or possibly something else (unlikely but still make sure).
