Hydrocephalus is a very frightening presence for people, especially fetuses, whose vitality is often very fragile. Hydrocephalus fetuses in pregnant women have various symptoms. So, what are the symptoms of hydrocephalus in pregnant women's stomachs? What are the causes of fetal hydrocephalus? Next, the editor will provide a detailed introduction for everyone.
What are the symptoms of hydrocephalus in a pregnant fetus
1. Subdural hematoma or effusion in infants. Mostly caused by birth injuries or other bleeding factors, it can be unilateral or bilateral, and is commonly found in the parietal region. Chronic cases can also cause the head to enlarge and the skull to become thinner. Anterior fontanelle puncture can be used for differentiation, and bloody or pale yellow fluid can be extracted from the subdural space.
2. Rickets. Due to irregular thickening of the skull, the frontal and occipital bones protrude, forming a square skull that appears to be enlarged. But this disease does not have symptoms of increased intracranial pressure, but has other manifestations of rickets, so it is different from hydrocephalus.
3. Underdeveloped brain. Although the ventricles have also expanded, there is no abnormal increase in head circumference. Prominent manifestation is dementia without symptoms of increased intracranial pressure.
4. Hydrostatic anencephaly. CT scan can be used for differentiation. When there is hydrocephalus with anencephaly, the CT scan shows no cerebral cortex except for the occipital area, and prominent basal ganglia can be seen.
5. Giant brain malformation. It is an abnormal increase in the weight and volume of the brain itself caused by various reasons. Some primary giant brains may have familial characteristics, with or without cellular structural abnormalities. Although the head of this disease is relatively large, there are no symptoms of increased intracranial pressure, and CT scans show normal ventricular size.
What are the causes of fetal hydrocephalus
1. Excessive cerebrospinal fluid production: In addition to papillary tumors of the choroid plexus in the ventricular system, diffuse villous hyperplasia of the choroid plexus is an extremely rare cause of excessive cerebrospinal fluid production.
2. Cerebrospinal fluid absorption disorders: Children with intracranial hemorrhage or central nervous system infection may experience skull base subarachnoid adhesions, leading to reduced absorption of cerebrospinal fluid by arachnoid granules. The vast majority of hydrocephalus is caused by cerebrospinal fluid absorption disorders.
3. Obstruction of cerebrospinal fluid circulation channel: It is caused by congenital or acquired factors, and cerebrospinal fluid circulation channel obstruction includes intraventricular obstruction and extra ventricular obstruction.
The above is some information about fetal hydrocephalus that the editor has introduced to you. Is there anything else that you don't understand after listening to the editor's introduction? Friends interested in this area can seek advice from doctors. Physical health is the most important thing, and money is an external object. The body is the capital of revolution.
