32 male. c & l x-ray = scoliosis but brain & c spine mri normal. b12 @ 1100. suffering from lhermitte's sign. what other tests can determine cause?

Anatomy: If you do indeed have a true lhermitte's phenomenon, it represents spinal cord irritation over the posterior column, and a cause is always present, but sometimes obscure. Do you have vertebral body instability in neck, (perhaps flexion/extension films), is there diabetes (hgb-a1c), might you have an arteritis (ana profile)? Sometimes, spinal fluid analysis is answer (ms profile).

Myelogram: A myelogram with postmyelogram ct scan with flexion and extension views of the cervical spine would be the most sensitive test for spinal cord impingement. If that was negative, it suggests the cause of your symptoms may not be spinal cord impingement and may be from a neurological condition.
