“Our June since the age of three has often lumbosacral pain, pain in the place can not be pressed can not be rubbed otherwise the child can be painful crying. Because the pain is also a bout of good and bad, so has not been taken seriously.” 2014 has been ten years old Jun Jun has been six years of lumbosacral pain. It was only after Jun’s own strong request that mom and dad took Jun to the local hospital. An MRI of the lumbosacral region at the local hospital revealed a sacral cyst. In order to give her better treatment to make up for the years of neglect, Junjun’s parents took her to see Prof. Yan Yi of the Department of Spinal Neurosurgery at the First Affiliated Hospital of Chongqing Medical University. After Prof. Yan’s examination, Jun Jun was initially diagnosed with sacral cyst, congenital sacral bifida, and end-filament tension syndrome. Sacral cyst fistula ligation and end-filament amputation were recommended. Professor Yan introduced sacral cysts are spinal cysts, although they are not tumors and will not be malignant, but the increased pressure of cerebrospinal fluid in the cysts will compress the surrounding sacral nerves, bone, and in severe cases, will also cause bone destruction. If the cyst continues to compress the peripheral nerve fibers, the patient may suffer from abnormalities in perception, motor function, and even urinary and defecation function. On Prof. Yan’s advice, Junjun’s parents agreed to operate on Junjun. The surgery took 2 hours and was successfully completed. Ten days later, the lovely June was discharged from the hospital accompanied by her parents. The disease that had been troubling June for six years was finally cured by Prof. Yan. Prof. Yan said that most sacral cysts are congenital, and he hoped to tell parents not to ignore their children’s lumbosacral pain through this incident. Compared with adults, children have a relatively poor ability to express themselves and need more care and attention.
