Patients with spinal cord embolism syndrome, especially children, should be alerted to one of the clinical manifestations of the disease: hairy, abnormally pigmented skin in the lumbosacral region. Tethered cord syndrome (TCS) is a syndrome in which the spinal cord or cones are strained due to a variety of congenital and acquired causes, resulting in a series of neurologic dysfunctions and malformations. Since the spinal cord is mostly pulled in the lumbosacral cord, causing the cones to be abnormally low, it is also called low spinal cord. Common examination of lumbosacral skin hirsutism and abnormal pigmentation: 1, urinary follicle stimulating hormone Follicle Stimulating Hormone (FSH) and LH are collectively known as gonadotropins, and TSH belongs to the same class of glycoproteins, which promotes follicular maturation and promotes the secretion of estrogen together with LH to cause ovulation, and synergizes with testosterone to promote the production of testicular seminiferous tubules and spermatogenesis, as well as the formation of spermatogenesis. It is secreted in pulses and changes with menstrual cycle in women. 2.Spine MRI examination Spine MRI examination is the diagnosis of spine and spinal cord disease correct rate of MRI is significantly higher than CT, the source of the disease is displayed, localization is accurate, can be used as the preferred method of examination. Spinal MRI examination can accurately evaluate the spine and various pathologies, and has diagnostic significance for spine and spinal cord diseases. 3, adrenocorticotropic hormone (ACTH) excitability test Adrenocorticotropic hormone (ACTH) excitability test is carried out through: ① 8 hours of static drip method, and then measure the urinary free cortisol; ② rapid method, blood sampling to detect the cortisol of these two methods of a test. The response is normal in polycystic ovary syndrome, whereas 17-ketosterol and 17-hydroxysterol are significantly higher in those with abnormal adrenocortical function.
