The symptoms of spinal cord deformity mainly include: 1. Spinal cord hemorrhage: The patient suddenly experiences severe pain in the neck or lumbar or back, sudden inability to move the arms and legs, and sometimes has difficulty with bowel and urine. 2. Spinal cord ischemia: The patient has no strength in the arms and legs, feels numb, has poor control of bowel movements and urination, or develops impotence and other symptoms. Clear spinal cord deformities are not difficult to diagnose when some abnormal blood vessels can be seen on MRI, but many spinal cord deformities do not have obvious abnormal blood vessels on MRI and often show edema of the spinal cord, which is then very easy to misdiagnose as orthopedic or neurological diseases such as lumbar disc herniation, multiple sclerosis, etc. Due to wrong diagnosis and delayed treatment, the patient may finally lose the time for treatment and Complete paralysis may occur. In addition, spinal vascular malformation is very specialized and the risk of treatment is very high, so patients must go to a hospital with a high level of expertise for diagnosis and treatment.
