Abnormal buildup of cerebrospinal fluid (CSF) in the brain, which can result in brain damage or death, is called hydrocephalus. Read the article to know more.
The brain has two circulations.
However if CSF collects in excess and is not reabsorbed, then pressure inside the skull can increase to damage brain cells or even kill them by depriving them of oxygen and glucose.
After the age of 2 years, the skull bone plates join together so that the head can no longer enlarge in response to CSF accumulation. Subsequently, the pressure inside the skull, called intracranial pressure (ICP), increases and thus reduces the blood flow to the brain as well as causing physical changes to the brain. Deformity of the nerves from increased pressure causes loss of vision, difficulty in thinking, difficulty with coordination and loss of memory. If unchecked it can lead to shifts of brain structures, called herniations, which can result in permanent coma or death.
If the pressure remains above that which allows blood flow into the brain for even a few minutes, then a condition where the brain essentially dies, called brain death, will occur.
There are thousands of people around the world living independent and useful lives following successful surgery for hydrocephalus.

Answer: Hello, Welcome to icliniq.com. Mild hydrocephalus is possible at term and if the biparietal diameter on ultrasound is less than 10 cm then it is still fine. Ideally targeted scan can be done to check for any aqueductal stenosis congenitally, but it is unlikely. The size of the biparietal diameter sh... Read Full

Answer: Hi, Welcome to icliniq.com. This is a very rare anomaly. Dilatation of entire vein is more common. Theoretically, there is a risk of rupture. But, in practice the most common complications are hydrocephalus and cardiac problems. You have not indicated whether the scan revealed hydrocephalus or not. ... Read Full
Query: Hi doctor, My present ultrasound is showing mild hydrocephalus with breech presentation (36 weeks) dilated 13 mm ventricle. No genetic disorder reported earlier done in second trimester. All the previous ultrasound showed normal and sound growth of fetus. Reports attached for your reference. Thank y... Read Full >>
Answer: Hello, Welcome to icliniq.com. Hydrocephalus means increase in fluid content in the fluid spaces of the brain. This can keep increasing in size or remain same. Hydrocephalus was detected in the last trimester. As it is now 36 weeks wait for baby to get delivered. As there is fetal hypoxia your obste... Read Full
