Localisation of Spinal Cord Level in Transverse Myelitis

In this article we will discuss the Localisation of Spinal Cord Level in Transverse Myelitis

In this article, we will discuss the Localisation of Spinal Cord Level in Transverse Myelitis. So, let’s get started.

Cervical cord (Quadriplegia)

  1. High cervical cord lesions (C1-C4) are characterized by UMN type of quadriparesis with or without respiratory muscles or diaphragmatic paralysis. Patient may complaint of suboccipital pain radiating to neck and shoulder
  2. Lesion of C4-C5 produces UMN type of quadriparesis with preserved respiratory function
  3. Lesion of C5-C6 causes quadriplegia with loss of biceps and supinator jerks while other jerks (triceps and lower limbs) are exaggerated and abdominal reflexes are lost
  4. Lesion of C7 produces quadriparesis with loss of triceps jerks, normal biceps and supinators; and exaggerated lower limb jerks and loss of abdominal reflexes
  5. Lesion of C8 causes loss of finger flexion with exaggeration of deep tendon jerks in the lower limbs. Other upper limb tendon reflexes are normal. Abdominal reflexes are lost

Thoracic cord (Paraplegia)

  1. Lesion above T6 produces paraplegia with exaggerated deep tendon jerks and loss of abdominal reflexes. The upper most level of the lesion is decided by sensory loss over the chest
  2. Lesions of mid thoracic cord (T6-T9) produces loss of upper abdominal reflexes. The umbilicus is pulled downwards due to contraction of lower abdominal muscles. There is UMN type of paraplegia (deep jerks are variable or brisk)
  3. Lesions at T9-T10 produces paraplegia with loss of lower abdominal reflexes with preserved upper abdominal reflexes. There is upward movement of umbilicus due to contraction of upper abdominal muscles. There is UMN paraplegia.
