The 14-year-old Renren, ten days ago to the mother shouted leg numbness, front and back are feeling pain. The family’s only daughter, the mother and father did not dare to neglect the family’s “little princess”. The company’s main business is to provide a wide range of products and services to the public. ”My child was originally spoiled, very delicate. Usually I and her grandmother take turns to take care of the hospital. Three days ago the child had to be supported to go to the toilet, I think the condition has worsened. I should have known that I would have taken the child to the hospital earlier, who would have thought that the child now can not take care of urine ……” looking at the mother of love lying in the hospital bed full of tears. Renren was admitted to the Department of Spinal Neurosurgery of the First Hospital of Chongqing Medical University for “chest and back pain, numbness of both lower limbs for ten days and weakness of both lower limbs for three days”. Prof. Yan Yi learned that the patient could still walk with assistance three days ago, but was now paralyzed in bed with urinary incontinence. Prof. Yan read the MRI report in detail and made a diagnosis: an occupying lesion in the spinal canal at the level of thoracic 3. As the spinal cord was severely compressed at the lesion, local circulation was blocked and spinal edema was evident, leading to a dramatic worsening of the patient’s condition. Professor Yan suggested that Ren Ren should be operated immediately to release the spinal cord compression and save the patient’s spinal cord function as soon as possible. During the operation, it was found that the spinal cord of Renren’s thoracic 2 segments was severely compressed, and the tumor was closely attached to the spinal cord, and the blood supply was very rich, which made the operation very difficult and risky. After a delicate surgery, the tumor was finally removed and the spinal cord compression was completely lifted. After the surgery was successfully completed, Ren Ren was transferred back to the neurosurgery ward to continue her rehabilitation treatment. On the third day after the surgery, Renren’s chest and back pain had been relieved, the muscle strength of both lower limbs had been significantly restored, and the sensation below the chest had become more sensitive. The family was relieved to see a happy smile on their faces.
