What should be done for widened bilateral lateral ventricles in a newborn?

　　Bilateral ventriculomegaly in newborns refers to an enlargement of the cerebrospinal fluid spaces within the lateral ventricles of the infant's brain. In most cases, bilateral ventriculomegaly in newborns may be associated with congenital factors, genetic factors, infections, birth injuries, or abnormal brain development, and can be treated with medications and rehabilitation training. Specific details are as follows:

　　1. Congenital factors: Some newborns may be born with enlarged lateral ventricles, which could be related to abnormal brain development or structural issues during embryonic development.

　　2. Genetic factors: In some cases, familial genetic factors may lead to lateral ventriculomegaly in infants, especially when there is a family history of inherited neurological disorders.

　　3. Infections: Certain infections, particularly those occurring during fetal development—such as cytomegalovirus, toxoplasmosis, or syphilis—can adversely affect brain development in newborns and result in ventriculomegaly.

　　4. Birth injury: If a newborn experiences head trauma during delivery, such as intracranial hemorrhage or skull fracture, these injuries may lead to enlargement of the lateral ventricles.

　　5. Abnormal brain development: During fetal development, if certain areas of the brain fail to develop normally or exhibit abnormalities, this may cause ventriculomegaly. Such developmental anomalies may include neural tube closure defects or other malformations in the fetal brain.

　　For the above conditions, treatment under medical supervision may include medications such as mannitol injection or cerebral protein hydrolysate injection, along with functional exercises to support recovery. Parents should actively cooperate with physicians during treatment.
