Bregma closure delay
Introduction
Introduction Thinning of the skull, separation of the cranial suture, and delayed or enlarged anterior and anterior iliac crest are common clinical symptoms of hydrocephalus. The diseases associated with the anterior ankle closure delay are neonatal asphyxia, spina bifida, meningitis, hydrocephalus, congenital hydrocephalus, and cerebellar tonsil. Symptoms associated with this are intracranial space-occupying lesions, hydrocephalus, abscesses, delayed anterior ankle closure, and enlarged head. Advocating the appropriate age for childbirth According to relevant data, the incidence of hydrocephalus teratility tends to increase with the age of pregnant women. Generally, the incidence rate is the lowest in the 25-29 age group, but the difference is not significant. The incidence rate increases after 30 years old. Therefore, promoting the appropriate age to have a certain significance for the prevention of hydrocephalus.
Cause
Cause
1) Congenital malformations: such as midbrain aqueduct stenosis, decidual formation or atresia, interventricular pore atresia (fourth ventricle median or lateral occlusion), cerebral vascular malformation, spina bifida, cerebellar tonsil sac.
2) Infection: Intrauterine infections such as various viruses, protozoa and Treponema pallidum meningitis are not controlled early, hyperplastic fibrous tissue obstructs the circulation of cerebrospinal fluid, or intracranial inflammation of the fetus can also make the brain pool and arachnoid The lower cavity and arachnoid adhesions are occluded.
3) Bleeding: Fibrosis caused by intracranial hemorrhage, malabsorption of intracranial hemorrhage due to birth injury.
4) Tumor: Any part of the cerebrospinal fluid circulation can be blocked, more common in the vicinity of the fourth ventricle, or choroid plexus papilloma.
5) Others: Certain hereditary metabolic diseases, perinatal and neonatal asphyxia, severe vitamin A deficiency, etc.
Examine
an examination
Related inspection
Brain CT examination
1. Cranial X-ray showed cranial cavity enlargement, thinning of the skull and separation of cranial sutures.
2. Ventricular gas or water-soluble iodine imaging, showing the shape and size of the ventricular system, as well as the thickness of the cerebral cortex.
3. Two-dimensional ultrasound examination of the skull showed no shift of the midline wave and enlargement of the ventricular system.
4. CT or MRI scan showed that the ventricular system was significantly enlarged, and sometimes the cause of hydrocephalus could be detected.
Diagnosis
Differential diagnosis
Differential diagnosis of anterior ankle closure delay:
1. Immature children: The head enlarges faster, some resembles hydrocephalus, but the ventricles are not large.
2. Rickets: The skull is mostly square and has other symptoms of rickets.
3. Malformed head: The head is large, the growth is fast, there is obvious mental deficiency, no eyeball drooping phenomenon, ventriculography is normal.
4. Chronic subdural hematoma: the head enlargement is slower, more red or yellow liquid can be seen under the dura mater, and there is bleeding in the fundus. CT can confirm the diagnosis.
5. Intracranial space-occupying lesions such as tumors, abscesses, etc.
