Distinguishing cervical transverse myelitis with spinal shock from Guillian Barre syndrome is that in the

(A) Sharp level of demarcation of sensory and motor symptoms existb> Well defined transverse level on trunk - below which there is sensory and motor loss is a feature of spinal cord lesion.> Transverse myelitis is sometimes manifested as rapid-onset, severe paraparesis or quadriparesis with areflexia, which may lead to diagnostic con-fusion with other causes of ascending weakness,such as the Guillain-Barre syndrome; otherwise, hyperreflexia and Babinski signs are present, con-firming a central rather than a peripheral cause of the muscle weakness. A well-defined truncal sensory level, below which the sensation of pain and temperature is altered or lost, distinguishes myelopathy from cerebral lesions and peripheral neuropathies.> Neuropathic pain may occur in the midline (an aching, deep pain) or in a dermatomal distribution (radicular or lancinating pain or a sensation of burning or itching), with the latter pattern providing a clue to the anatomical level of the lesion.
