Demyelinating lesions of the cervical spinal cord

Introduction Demyelinating cervical spinal cord disease is a disease in which the cervical spinal cord is compressed and damaged by the nerve center. When the disease is serious, it can invade the spinal cord anterior horn cells and brainstem nucleus and the brain motor cortex pyramidal cell crisis life.

Cause

Maintaining a fixed posture for a long time, causing the cervical disc to be compressed after the cervical disc is protruded.

an examination

Spinal MRI examination, neck test, cervical CT examination, Hoffman sign

First, medical history and symptoms:

Many young and middle-aged patients have symptoms of respiratory infection or vaccination within two weeks before the disease. There are causes of cold, overwork, trauma and other causes. The first symptom was numbness and weakness in the lower limbs, back pain and banding in the corresponding parts of the lesion, urinary retention and fecal incontinence.

Second, auxiliary inspection:

1. The white blood cell count in the peripheral phase of the acute phase is normal or slightly higher.

2. Cerebrospinal fluid pressure is normal, some patients have mildly increased white blood cells and protein, and normal sugar and chloride content.

3. Spinal MRI showed thickening of the spinal cord and abnormal signal.

Differential diagnosis

Differential diagnosis of cervical spinal cord demyelinating lesions:

1. Cervical epidural lesions: Cervical epidural lesions are one of the clinical manifestations of spinal cord compression. Myelitis is a group of spinal cord, spinal nerve roots and their supply vessels that are caused by various types of lesions. Illness.

2, complete cervical spinal cord injury: cervical spinal cord injury refers to cervical spine fractures and other cervical spinal cord injuries, manifested as limbs and trunk of varying degrees of paralysis, dysfunction. Patients often have difficulty in breathing due to respiratory muscle spasm, chest tightness, etc., and because of orthostatic hypotension are prone to dizziness, vertigo, and palpitation. Cervical spinal cord injury is divided into complete injury and incomplete injury according to the degree of injury. Complete injury is that there is no sensation when the pointer stabs the anus, and there is no voluntary contraction of the external anal sphincter during anal examination. Incomplete injury is the feeling when the pointer stabs the anus, or the anal external sphincter has an arbitrary contraction when the anus is diagnosed. Usually, the sensory function and motor function of the limbs after cervical spinal cord injury will be restored to varying degrees.

3, upper cervical medullary lesions: upper cervical medullary lesions due to spinal cord tumors in the cervical spinal cord region two lesions, upper cervical medullary lesions may have occipital, neck pain and paresthesia.
