This video shows Fetal Hydrocephalus with a pregnancy of about 12 weeks 5 days.
Hydrocephalus is typically detected through a prenatal ultrasound between 15 and 35 weeks gestation. But here in this case fetus is of about 12 weeks 05 days.
It can be present at birth (congenital) or occur after birth (acquired). Pediatric hydrocephalus can be damaging if left untreated, but with early diagnosis and treatment, children with hydrocephalus can often lead normal healthy lives.
Traditionally, fetal hydrocephalus has been detected prenatally using sonographic measurements of the enlarged ventricles. The most useful measurement is the transverse atrial width, which is normally between 4-8 mm with a normal upper limit of 10 mm.
Fetal Hydrocephalus. Hydrocephalus, or “water on the brain,” is a condition associated with a buildup of cerebrospinal fluid (CSF) in or around the brain. It could be diagnosed even before a baby is born, and maybe treated using minimally-invasive surgical techniques.
Hydrocephalus occurs when CSF builds up within the ventricles of the brain, causing them to grow progressively larger. Benign macrocrania of infancy is a more common condition in which a baby can have mild ventriculomegaly and a large head, but not hydrocephalus.
Approximately 1 in every 500 American babies is born with hydrocephalus. It may be caused by an infection in the mother during pregnancy, such as rubella or mumps, or a birth defect, such as spina bifida. It is one of the most common developmental disabilities, more common than Down syndrome or deafness.
The following are the most common symptoms of hydrocephalus in babies. Bulging eyes and an inability of the baby to look upward with the head facing forward. Prominent scalp veins. Increased irritability.
Traditionally, hydrocephalus is detected and treated after birth with a shunting procedure. However, with the advent of high-quality prenatal ultrasonography, ventricular enlargement is now routinely diagnosed in utero. It accounts for up to 20 percent of cases of fetal hydrocephalus.
Many children with pediatric hydrocephalus have normal intelligence and physical development, but some may be slower to develop skills such as hand-eye coordination or learning to walk. Some may experience learning problems as they progress in school.
In many cases, hydrocephalus doesn't develop until the third trimester of the pregnancy. Ultrasounds done earlier in pregnancy may not show this condition. Children with this condition may be likely to have developmental delays.
The causes of hydrocephalus are still not well understood. Hydrocephalus may result from inherited genetic abnormalities (such as the genetic defect that causes aqueductal stenosis) or developmental disorders (such as those associated with neural tube defects including spina bifida and encephalocele).
