What are the main factors that can lead to hydrocephalus in the fetus?

Patient's question:

Hydrocephalus of the fetus, polyhydramnios, developmental delay

Doctor's answer:

Analysis of the condition: Fetal intrauterine infection, such as various viral, protozoal, and syphilitic meningitis that has not been controlled early, can lead to proliferated fibrous tissue blocking the channels of cerebrospinal fluid circulation, or intracranial inflammation in the fetus can also cause adhesion and occlusion of the cisterns, subarachnoid space, and arachnoid granulations.
Recommendations: If there is no congenital genetic predisposition, the likelihood of getting this disease in a subsequent pregnancy is not very high. It is advisable to avoid gynecological diseases and undergo thorough prenatal physical examinations.
