Syringomyelia formation
Introduction
Introduction Syringomyelia, also known as syringomyelia, is a slow-moving spinal degenerative disease; it is characterized by the formation of vacuoles and gliosis in the spinal cord. Syringomyelia usually begins slowly and progressively worsens. Patients often see symptoms due to pain, numbness in the upper limbs and trunk, upper limbs, especially hand weakness, muscle atrophy, or inflexible movements. There are no consistent and accurate understandings of the specific causes of syringomyelia and lateral sclerosis. It can be divided into congenital and acquired congenital, congenital and cerebellar tonsil malformation type I, acquired conspiracy, tumor, inflammation, etc. cause.

Syringomyelia usually begins slowly and progressively worsens. Patients often see symptoms due to pain, numbness in the upper limbs and trunk, upper limbs, especially hand weakness, muscle atrophy, or inflexible movements.
The clinical manifestations of syringomyelia can be divided into the following three aspects:
1. Symptoms of onset: Because the syringomyelia is often on the basal part of the posterior horn of the neck, the onset is often numbness, pain, muscle weakness and headache of the neck and shoulders of one side, and muscle atrophy of the hand. For many years, there are often people who suffer from pain or temperature loss and burn their hands or burn without knowing the pain. In addition, there are stiff and weak limbs, numbness, difficulty walking, or abnormal facial and body perspiration, and a few cases have dizziness. , double vision or fall.
2, feeling abnormal: usually manifested as one side or both sides of the upper limb pain and temperature sensation diminishing or disappearing; or may have numbness, severe hands are burned or knife cuts are not aware; or accompanied by neck, shoulders, back or Pain in the upper limbs. Some patients also have paresthesia in the lower extremities.
3, abnormal movement: mainly manifested as one or both sides of the upper limb strength decreased; hand muscle atrophy, severe small finger and ring finger can not straighten, the hand is claw-shaped; neck, shoulder, arm muscle atrophy. Some patients have lower extremity dyskinesia. Patients with persistent or untreated symptoms may be paralyzed in the advanced stages.
Diagnosis
Differential diagnosis
Differential diagnosis:
1. Spinal cord ischemia: A series of damaging biochemical changes caused by spinal cord ischemia will lead to intracellular calcium accumulation and increased oxygen free radical content, thereby damaging neurons in the spinal cord and causing irreversible damage to the spinal cord. Spinal cord ischemia is rarer than cerebral ischemia. The main reason is that spinal arteriosclerosis is less than cerebral arteries; spinal cord blood supply network is abundant, and spinal cord has strong tolerance to ischemia. Spinal cord ischemia caused by lesions in the spinal cord itself, the symptoms may be transient or permanent. After the spinal cord ischemia is gradually severe, it can also be progressive paraplegia, resulting in a sensory loss plane and sphincter disorders such as the bladder.
2. Transverse spinal cord injury: Spinal cord dysfunction caused by infection or infection-induced spinal cord dysfunction leads to nerve impulse blockade of all or most of the nerve bundles, limited to several segments of acute transverse spinal cord inflammation. Most are ill after acute infection or vaccination. It is characterized by paralysis of the limbs below the level of spinal cord lesions, loss of sensation and dysfunction of the bladder, rectum and autonomic nerves. It is one of the common spinal diseases. The onset can be seen in any season, but it is more common in late winter and early spring and late autumn and early winter.
