Hi there, my dad has been experiencing electric shock type feelings from his neck down his left leg that were originally diagnosed at focal seizures, than the shocks started to spread to both of his legs and cause dizziness. The doctor than diagnosed him with myoclonic seizures. He had an MRI of his cervical spine and from c4-6 there is a compression of the spine. When reviewing the MRI with the neurosurgeon they noticed that not only was the compression present but also a white streak down the cervical spine and partially into the thoracic spine but the MRI didn t show enough of the spine. What does this white streak typically suggest?
