The examination of myelitis is done through the following aspects
There are many clinical symptoms of myelitis, mainly manifested as sensory loss, dysfunction of rectal function, and limb paralysis. At this time, timely treatment is needed. When diagnosing myelitis, what examination methods can be used?
⒈ Lumbar puncture: Cervical compression test is unobstructed, and in a few cases, severe spinal cord edema can lead to incomplete obstruction. CSF pressure is normal, appearance is colorless and transparent, cell count and protein content are normal or slightly increased, mainly lymphocytes, and sugar and chloride are normal.
⒉ Imaging examination: X-ray of the spine is normal. MRI typically shows thickening of the spinal cord at the lesion site, multiple patchy or dot-like lesions in the spinal cord segments, showing T1 low signal, T2 high signal, uneven intensity, and sometimes fusion. Some cases may remain without any abnormalities.
①. Spinal cord MRI: It can be seen that the spinal cord is swollen, with uneven long T1 and long T2 signals.
②. Spinal cord CT: It is often combined with myelography. It can be seen that the spinal cord is slightly thickened, with uneven density.
③. Myelography: How to check myelitis? Commonly seen diffuse swelling of the spinal cord, or it may be normal. It is mainly used for cases with atypical clinical manifestations, and to differentiate from other diseases. Examination during the acute stage can lead to exacerbation of the condition.
⒊ Electrophysiological examination:
① Visual evoked potential (VEP) is normal, which can be distinguished from optic neuritis and MS.
② The amplitude of somatosensory evoked potential (SEP) can significantly decrease; motor evoked potential (MEP) is abnormal, which can be used as an indicator for judging efficacy and prognosis.
③ Electromyogram shows denervation changes.
4. Blood count:
⑴ Blood routine: During acute attacks, the number of white blood cells can increase, mainly polymorphonuclear leukocytes.
⑵ Erythrocyte sedimentation rate: It can accelerate during the acute attack period.
⑶ Immunological indicators: During acute attacks, the ratio of Th/TS (helper T cells/suppressor T cells) in peripheral blood increases, the level of total complement increases, and the level of immunoglobulins increases. These tend to decrease as the condition improves.
