Question

a tubular cavity in the spinal cord that may develop following spinal cord injury that produces dissociated anesthesia with a cape - like distribution initially, but eventually leads to quadriplegia.
polio myelitis
acute spinal cord syndrome
lambert - eaton syndrome
epidural abscess
syringomyelia

Explanation:

Syringomyelia is a condition where a fluid - filled cavity (syrinx) forms in the spinal cord. After spinal cord injury, it can cause dissociated anesthesia with a cape - like distribution initially and may progress to quadriplegia. Poliomyelitis affects motor neurons due to a viral infection. Acute spinal cord syndrome is a general term for sudden spinal cord damage without the specific cavity feature. Lambert - Eaton syndrome is a neuromuscular junction disorder. Epidural abscess is a collection of pus in the epidural space.

Answer:

E. Syringomyelia
