Crestal cremasteric bulge is a common partial cremasteric fracture, which refers to the bulging of the cremasteric membrane and/or cremasteric nerve tissue in the spinal canal outward; if the cremasteric nerve tissue bulges at the same time as the cremasteric membrane and the bulging capsule is covered by intact skin or pseudoepithelium, it is called cremasteric cremasteric bulge. Cricoid membrane and crestal crestal myelomeningocele occur in the dorsal midline of the crestal column, most commonly in the lumbosacral segment, and rarely in the cervical or thoracic segment. In individual cases, there is a lateral protrusion from the paravertebral area through the enlarged intervertebral foramen into the spinal canal, or the bulging capsule extends into the posterior pharyngeal wall, thoracic cavity, abdominal cavity, and pelvic cavity. Crestal bulge is usually solitary and multiple cases are less common. Cricoid membrane bulge sometimes coexists with congenital hydrocephalus. The main symptoms of patients with cremasteric bulge and cremasteric crural bulge are localized masses and signs of neurological damage. In addition, a small number of patients with cremasteric bulge and cremasteric medullary bulge have symptoms of mass and compression of internal organs as the bulge extends into the thoracic, abdominal, and pelvic cavities. Some children with cremasteric bulge have hydrocephalus and other malformations with corresponding symptoms. The examination of cremasterocephaly and cremasterocephaly requires the use of imaging tests, such as cremasterocephalography, CT examinations and cremasterocephalography MRI. CT, MRI, and PET-CT scans can clearly show the cremasteric fissure and the deformity of the cremasteric medulla and nerves, as well as local adhesions and other pathologies. In principle, the treatment of patients with cremasteric crepitus and cremasteric myelomeningocele should be surgical, and usually the earlier the surgery, the better the results. The main goal of surgery is to remove the bulging capsule and repair the soft tissue defect to relieve the patient’s symptoms. Postoperative antibiotics are used to prevent infection and to prevent leakage of cerebral crest fluid in order to ensure the success of the repair.
