Abstract: Background: Anencephaly is a neural tube defect which is due to the defective closure of Anencephaly can be diagnosed by ultrasound examination . Apa itu anencephaly? Anencephaly adalah cacat lahir yang serius di mana bayi dilahirkan tanpa bagian otak dan tengkorak. Ini adalah jenis neural tube defect. The two most common neural tube defects are spina bifida and anencephaly. In spina bifida, the fetal spinal column doesn’t close completely. There is usually.

Hydranencephaly is one of several types of cephalic disorders. These disorders derive from either damage to, or abnormal development of, the fetal nervous system in the earliest stages of development in utero. Hydranencephaly does not have any definitive identifiable cause factor.

As with all cephalic conditions, there is an obvious interruption in normal development of the nervous system. A traumatic occurrence of sorts, resulting in prenatal stroke, is believed to be the primary cause of hydranencephaly.

Anence;haly researchers have also suggested the possibility of a genetic component, though only one case has been documented in which a family has been presented this diagnosis for more than one child.

The prognosis for a child born with hydranencephaly is presented as very poor: While some children given this diagnosis may not survive past their first birthday, each case is unique and anence;haly are a growing number of cases where children can defy this prognosis and live several years. The oldest individual with a confirmed case of hydranencephaly celebrated his 33rd birthday before his passing.


A diagnosis can be made in utero, though often inaccurate or unconfirmed until birth. In other cases, diagnosis is delayed for several weeks or even months since the infant appears developmentally normal at birth. As the child matures, delays become much more apparent. In extremely rare cases, damage causing hydranencephaly can occur in infancy following infections such as meningitis, stroke, intracerebral hemorrhage, and traumatic brain injury.

Neural Tube Defects

Not all apparent signs are identifiable at birth. Despite the generalized prediction of complications at birth, or even before birth resulting in death, many children display none initially.

Symptoms such as increased irritability, increased muscle tone, and the lack of purposeful movement generally initiate suspicion of an underlying cause. Seizures, reduced ability to such effectively, inability to maintain body temperature, the suspicion of visual avalah, failure to thrive or lack of growth, involuntary xdalah, chronic respiratory and gastrointestinal complications, obvious cerebral palsy, and global delays may present themselves as the child ages.

Still other infants display no obvious symptoms at birth, going many months without a confirmed diagnosis of hydranencephaly. In some cases a severe hydrocephalus, or other cephalic conditions, diagnosis aneencephaly misdiagnosed.


There is no cure for hydranencephaly.

Treatment is symptomatic; meaning associated conditions are treated to ensure the best quality of life possible. While the inevitable cannot be avoided entirely; with proper management of these associated symptoms and a proactive care team, the ability for the child to thrive is far greater. Surgery for placement of a shunt, in cases where hydrocephalus accumulation of excess cerebrospinal fluid is apparent, is advised.

While hydrocephalus is common amongst children given this diagnosis, several children display as microcephalic smaller than average cranial circumference or present as typical in appearance as well.
