Upper cervical spinal cord lesions
Introduction
Introduction The upper cervical medullary lesion is due to the lesion of the spinal cord tumor in the cervical spinal cord region. The upper cervical medullary lesion may have occipital, neck pain and paresthesia. Intraspinal tumors, also known as spinal cord tumors, include the origin of the spinal cord itself and various tissues (such as nerve roots, dura mater, blood vessels, adipose tissue, congenital embryonic residual tissue, etc.) adjacent to the spinal cord in the spinal canal. A tumor or metastatic tumor. May be closely related to heredity, trauma and the environment. The cause of the disease is mostly caused by specific virus invading the nerve. It is an immune disease, easy to relapse and delayed multiple sclerosis.
Cause
Cause
There is no clear cause of spinal cord tumors. It is speculated that it is not caused by a single cause and may be closely related to heredity, trauma and the environment. The cause of the disease is mostly caused by the invasion of the nerve by a specific virus. It is an immune disease that is prone to recurrence and multiple sclerosis. The cause of recurrence is that after hormone therapy and the original neurological insufficiency, the body's immunity is low. Early treatment is mostly treated with hormones and nutritional therapy, but the curative effect is difficult to control. Because of the recurrence of this disease, the nerves of the myelin sheath are re-damaged, which further aggravates the neurological symptoms. Delayed multiple sclerosis is a pathological change that occurs when the affected nerve is too long.

Periosteal reflex CT examination
Patients with the following clinical manifestations should consider the possibility of intracranial tumors and perform further imaging studies:
1. The sensation of numbness and pain and the loss of consciousness or the disappearance of the sense of touch, and the sensory disorder gradually develops from the top to the bottom.
2. The pain symptoms appear later and range.
3. May be associated with lower motor neuron symptoms, spinal cord hemisection syndrome is rare or not obvious.
4. The occurrence of spinal canal obstruction is late or inconspicuous, the protein content of cerebrospinal fluid is not obvious, and the symptoms are not obvious after the cerebrospinal fluid is released.
5. Spinal processes are rare, and bone changes in the spine are rare.
Diagnosis
Differential diagnosis
Differential diagnosis of upper cervical spinal cord lesions:
1, cervical spondylosis
The clinical manifestations of spinal cord tumors are very similar to cervical spondylosis, and spinal cord tumors are often overlooked due to the high incidence of spinal degenerative diseases. In this regard, clinicians should pay great attention to it. Spinal cord tumors often manifest as root pain and gradual spinal cord compression symptoms. It has a fixed site, severe pain, persistence, and increased coughing. At the same time or later, accompanied by stimulation or compression of the long spinal cord. Therefore, such patients should be routinely performed neurological examinations and corresponding imaging studies.
2, extramedullary tumor
Common clinical pathological types are neurofibromas and meningioma. Nerve root pain is more common and has the value of localization diagnosis. Feeling changes The sensory changes in the distal extremities are obvious, and develop from the bottom up, without sensory separation. The pyramidal tract sign appeared earlier and significantly, the symptoms of lower motor neurons were not obvious, and the spinal cord hemisection syndrome was more common. Early or obvious spinal canal obstruction, cerebrospinal fluid protein increased significantly, after the release of cerebrospinal fluid due to extramedullary tumors moved down and the symptoms worsened. Spinal processes are more common, especially epidural tumors, and spinal bone changes are more common.
