Question
Rewrite according to the ask column What are the common situations that can lead to hydrocephalus in children?
Answer
Rewrite according to the answer column Common Pathogenic Factors of Hydrocephalus in Children: Firstly, the most common cause is an excessive secretion of cerebrospinal fluid due to congenital hydrocephalus. The recognized theory is that the choroid plexus of the lateral ventricle is hyperplastic and excessively secretory, leading to a dysfunction in the secretion of cerebrospinal fluid, which in turn causes hydrocephalus. Second, there is a blockage in the absorption of cerebrospinal fluid, such as the blockage caused by fetal meningitis. Third, there is a blockage in the cerebrospinal fluid circulation pathway. Congenital malformations may be related to exposure to certain chemical substances, radiation, radioactive elements, early pregnancy fever, taking certain traditional Chinese medicine, abortifacients, fetal drugs, fetal position abnormalities, polyhydramnios, and so on. Common malformations include spina bifida, aqueductal stenosis of the midbrain, vascular malformations, etc. The spinal cord clefts or meningoceles or myelomeningoceles often accompany hydrocephalus.
