ascending skin numbness

Introduction

Introduction The extramedullary compression of spinal cord compression is characterized by pain or radiation pain in the compressed innervation area, sensory pathway pressure skin allergies or numbness, sensory disturbances ascending development, sphincter dysfunction appear later, exercise pathway compression zone There are cockroaches in the first place.

Cause

Cause

(1) Tumors: the most common, accounting for more than 1/3 of the total. Tumors located in the spinal canal of the epidural are more metastatic; benign schwannomas outside the subdural spinal cord, followed by neurofibroma, ependymoma; spinal cord tumors with glial Cell tumors are common.

(B) spinal lesions: spinal joints, strong spondylitis, rheumatoid arthritis, intervertebral disc prolapse, joint dislocation and spinal cord lesions caused by spinal tumor or tuberculosis destruction.

(3) Congenital malformations: such as Arnold-Chiari malformation, syringomyelia and hydrocephalus.

(D) inflammation: epidural abscess, spinal arachnoiditis and so on.

(5) Spinal vascular lesions: such as spinal vascular malformations, epidural hemorrhage, etc.

The diagnosis can be confirmed by myelography, lumbar puncture, spinal X-ray, CT, MRI, and the like. The symptoms caused by extramedullary lesions range from far to near, root pain, spinal tenderness, and late sphincter symptoms.

Extramedullary compression of the cone-shaped bundle on the disease side and the contralateral spinal thalamus bundle, that is, the diseased side limb weakness and the contralateral limb conduction-type sensory disturbance, called the spinal hemisection syndrome (Brown-Sequrd syndrome).

Extramedullary compression lesions, pain and temperature disturbances often start from the lower extremities and extend to the compression plane; intramedullary compression, sensory disturbances develop downward from the lesion segment, and the saddle zone feels retained until the end, which is called saddle avoidance.

Diagnosis

Differential diagnosis

Numbness of the limbs or trunk: numbness is a common symptom, which can be accompanied by other diseases, or it can occur alone. Common scalp numbness, numbness of the lips, numbness of the tongue, numbness of the limbs, numbness of the trunk and numbness of the body. And repeated attacks, long course, not easy to cure. The transmission of various sensations in the limbs of healthy people depends on the unimpeded access of the brain to the limbs. If there is a disorder in a certain part of this nerve pathway, symptoms such as limb numbness may occur. Patients with cervical spinal stenosis complained that there are fingers (mostly at the fingertips) or pain and numbness in the arm when the disease is first developed, especially tingling. Mainly due to the sensory disturbance caused by the involvement of the spinal thalamus bundle and other sensory nerve fiber bundles.

Numbness: refers to swelling, pain, numbness, not an isolated disease, often caused by other causes. Some people often have intermittent numbness or convulsions on their fingers or toes. In severe cases, they can spread to the whole body, and they will not heal for many years. Sometimes, although they can be better for a while, they can relapse. The symptoms are likely to be parathyroid diseases. Signs. Perceptual peripheral neuropathy, mainly manifested by varying degrees of numbness, pain, or abnormal sensation at the distal end of the extremities. The symmetry of the end of the finger, tingling, numbness and burning sensation is one of the manifestations of subacute combined degeneration of the spinal cord. Subacute combined degeneration of the spinal cord is a degenerative disease of the nervous system caused by vitamin B12 deficiency. Its clinical manifestations include deep sensory loss, sensory ataxia and spastic paralysis with spinal cord and lateral cord lesions, often accompanied by peripheral nerve damage. And the peripheral sensation of the symptoms.
