Usually encephaloceles are visible deformities and are diagnosed immediately after birth. Occasionally, a small encephalocele in the nasal or forehead region can go undetected. Sometimes encephaloceles are detected during a routine prenatal ultrasound, at as early as 13 weeks' gestation.

Full Answer

How is encephalocele diagnosed?

Prenatal diagnosis of encephalocele is accomplished by maternal screening of serum α-fetoprotein levels and ultrasound (US). With two-dimensional ultrasound (2D US), encephalocele appears as a defect in the calvarium containing a cystic or solid mass with a gyral pattern that is contiguous with the brain [2].

Can an encephalocele go undetected?

Usually encephaloceles are found right after birth, but sometimes a small encephalocele in the nose and forehead region can go undetected. An encephalocele at the back of the skull is more likely to cause nervous system problems, as well as other brain and face defects. Signs of encephalocele can include

What does encephalocele look like on ultrasound?

With two-dimensional ultrasound (2D US), encephalocele appears as a defect in the calvarium containing a cystic or solid mass with a gyral pattern that is contiguous with the brain [2]. When does an encephalocele form during human gestation? Encephalocele (pronounced en-sef-a-lo-seal) is a rare condition that happens before birth (congenital).

What happens if you have an encephalocele on your forehead?

Usually encephaloceles are found right after birth, but sometimes a small encephalocele in the nose and forehead region can go undetected. An encephalocele at the back of the skull is more likely to cause nervous system problems, as well as other brain and face defects. Seizures.

How is encephalocele diagnosed?

Most encephaloceles are diagnosed on a routine prenatal ultrasound or seen right away when a baby is born. In some cases, small encephaloceles may initially go unnoticed. These encephaloceles are usually located near the baby's nose or forehead.

How long do babies with encephalocele live?

Fetuses with an encephalocele are likely to die before birth. Approximately 21 percent, or 1 in 5, are born alive.

Can encephalocele be misdiagnosed?

This case highlights the uncommon site of anterior encephalocele; misdiagnosis and mismanagement of which could result in dreaded complications such as meningitis and cerebrospinal fluid leaking fistula formation.

How rare is an encephalocele?

Researchers estimate that about 1 in every 10,500 babies is born with encephalocele in the United States.

What are the symptoms of encephalocele?

Signs of encephalocele can include:too much fluid in the brain (called hydrocephalus)loss of strength in the arms and legs.a small head.awkward movement of muscles, such as those used in walking and reaching.delay in growth and development.problems seeing.problems with breathing, heart rate, and swallowing.seizures.

Is encephalocele genetic?

Encephaloceles are usually dramatic deformities diagnosed immediately after birth; but occasionally a small Encephalocele in the nasal and forehead region can go undetected. There is a genetic component to the condition; it often occurs in families with a history of spina bifida and anencephaly in other family members.

What are the chances of having another baby with encephalocele?

The recurrence risk of isolated encephalocele is 2% to 5%, but 10% if there are two affected siblings.

Can babies outgrow brain damage?

Children may be able to recover completely from mild cases of brain damage. However, severe cases can lead to lifelong disability and may require lifelong medical treatment. Severe newborn brain damage can lead to other conditions such as cerebral palsy.

What does encephalocele ultrasound look like?

Antenatal ultrasound An encephalocele may be seen as a purely cystic mass or may contain echoes from herniated brain tissue. If the mass appears cystic, the meningocele component predominates, while a solid mass indicates predominantly an encephalocele. Larger encephaloceles may show accompanying microcephaly.

Is encephalocele a brain tumor?

Encephaloceles arise from developmental defects in neural tube formation. These lesions contain brain and meninges which herniate through a defect in the skull. These may present as isolated malformations or rarely be associated with brain tumors.

What is the difference between anencephaly and encephalocele?

Anencephaly is often accompanied by spina bifida. Encephalocele is a protrusion of brain through a defect of the skull, usually in the occipital area. The protruding part is destroyed because of mechanical disruption and ischemia. The intracranial part of the brain around the defect is malformed and disrupted.

What does encephalocele ultrasound look like?

Antenatal ultrasound An encephalocele may be seen as a purely cystic mass or may contain echoes from herniated brain tissue. If the mass appears cystic, the meningocele component predominates, while a solid mass indicates predominantly an encephalocele. Larger encephaloceles may show accompanying microcephaly.

What is found in an encephalocele?

Encephalocele is usually a congenital type of neural tube defect, where a sac containing brain/meninges/cerebrospinal fluid forms outside the skull due to a bone defect. On occasions, acquired encephaloceles may result from trauma, tumors, or iatrogenic injury.

What is the difference between anencephaly and encephalocele?

Anencephaly is often accompanied by spina bifida. Encephalocele is a protrusion of brain through a defect of the skull, usually in the occipital area. The protruding part is destroyed because of mechanical disruption and ischemia. The intracranial part of the brain around the defect is malformed and disrupted.

What is the difference between Cephalocele and encephalocele?

Cephalocele is a generic term defined as a protrusion of the meninges with or without brain tissue through a defect in the skull. A meningocele is a protrusion of only meninges and cerebrospinal fluid (CSF). An encephalocele is a protrusion of meninges, CSF, and brain tissue.

What is Encephalocele?

Encephalocele (pronounced en-sef-a-lo-seal) is a rare condition that happens before birth (congenital). Normally, the brain and spinal cord form during the third and fourth weeks of pregnancy. They are formed out of the neural tube. Most encephaloceles happen when the neural tube does not fully close. This should happen when the baby’s brain, nervous system and skull are first starting to form. When the neural tube does not close, it can cause a sac-like bulge with brain tissue and spinal fluid that pokes through the skull. An encephalocele can be life-threatening. How serious it is, the treatment and the baby’s chance of living depend on where it is on the skull. Babies with an encephalocele often have chromosome, brain and facial problems as well. While scientists do not know what causes encephaloceles, there is proof that women who eat a lot of foods with folic acid (Vitamin B9) when they are pregnant are less likely to have a baby with the condition. Certain types of encephaloceles are also more common in women with diabetes.

How is Encephalocele Diagnosed?

Encephalocele is usually found during a prenatal ultrasound. If your doctor suspects your baby may have an encephalocele, you may have more tests that can provide information to help you and your doctors know what to expect when your baby is born. These tests may include:

What are the Signs and Symptoms of Encephalocele?

Once in a while, the condition is only discovered later in childhood, once a child starts to have physical or mental delays.

What are the Different Types and Locations of Encephaloceles?

Size, location and type of the encephalocele can greatly impact if the baby lives. It can also affect treatment options and physical and mental development.

What is the most common place for encephaloceles?

Occipital (at the back of the head). This is the most common place for encephalocele among babies born in the United States. This type of encephalocele is more common in girls. The outcome for these babies is poor. Fetal deaths and stillbirths are common. Those that live with occipital encephaloceles often have more problems, including delays in development, problems seeing, balance and coordination problems, hydrocephalus (fluid on the brain) and seizures

What is the condition where the neural tube does not close?

Encephalocele is a rare congenital condition where the neural tube does not close and causes a sac-like bulge with brain tissue and spinal fluid that pokes through the skull.

Why do doctors recommend genetic counseling?

Your doctor may recommend genetic counseling to discuss risks for a future pregnancy because encephalocele can be related to inherited disorders.

What is an encephalocele?

Encephalocele is an NTD characterized by a pedunculated or sessile cystic, skin-covered lesion protruding through a defect in the cranium (skull bone). Encephaloceles can contain herniated meninges and brain tissue (encephalocele or meningoencephalocele) or only meninges (cranial meningocele).

Can encephalocele be ruptured?

Skin covering – it is expected with encephalocele (but could be ruptured). Other anomalies – internal and external anomalies, including polydactyly, renal anomalies, etc. Cephalohematoma or caput succedaneum (benign scalp swelling) – can be confused with encephalocele.

Can encephalocele be confused with amniotic band?

Check if amniotic bands are mentioned – encephalocele might be confused with the amniotic band spectrum. The occurrence of other findings (facial schisis, limb and ventral wall anomalies, bands) points towards the diagnosis of amniotic band spectrum.

Where is the midline defect located?

Location – the midline defect will vary in location and size; the most common location is occipital (~74%), followed by parietal (13%). Covering – encephalocele is skin covered (unless a rupture has occurred). Herniation – may contain meninges and brain tissue (encephalocele) or meninges only (cranial meningocele).

Can encephalocele be diagnosed prenatally?

Prenatal. Encephalocele might be diagnosed prenatally using ultrasound but should always be confirmed postnatally. Use programme rules (SOPs) to decide whether to accept or not accept prenatal diagnoses without postnatal confirmation (e.g. in cases of termination of pregnancy or unexamined fetal death).

Can Meckel-Gruber syndrome occur with many genes?

Can occur with many single genes disorders (e.g., Meckel-Gruber syndrome) and with some chromosomal anomalies (e.g., trisomy 13, trisomy 18).

What is the axial T2WI MR?

Axial T2WI MR shows the classic appearance of a Petrous apex cephalocele (PAC) with direct communication between Meckel cave and the CSF intensity cephalocele in the anterior petrous apex .

What is the sagittal T1WI FS MR?

Sagittal T1WI FS MR shows a classic atretic parietal cephalocele with falcine vein and fluid collection . The fibrous stalk connecting the cephalocele through the calvarial defect is difficult to distinguish from the venous flow void.

What is the axial 3D bone CT of the calvaria?

Axial 3D bone CT of the calvaria in the same case demonstrates a small, focal, midline, interparietal calvarial defect representing the focal cranium bifidum through which the cephalocele communicates intracranially via the fibrous stalk.

How common is encephalocele?

Encephaloceles account for 10% to 20% of all craniospinal dysraphisms. The prevalence of encephalocele is approximately 0.8 : 10,000 to 4 : 10,000 live births,44–46 and is higher in Southeast Asia (2 : 10,000). 47 Overall, posterior encephaloceles are more common than anterior defects 44,48 but substantial ethnic differences exist: occipital cephalocele is more common in the Western hemisphere, whereas frontal cephalocele is more frequent in Asia, especially Thailand.

What is the protrusion of intracranial structures through a defect in the skull?

Encephalocele is the protrusion of intracranial structures through a defect in the skull. The herniated sac may contain meninges and brain tissue (encephalocele) or only meninges (meningocele).

What is temporal bone CT?

A temporal bone CT reveals a pedunculated encephalocele hanging through a focal dehiscence of tegmen tympani . This developed as a postoperative complication.

Where are encephaloceles most common?

These encephaloceles are more common in girls. Ninety percent of the encephaloceles seen in Southeast Asia are frontoethmoidal (sincipital). Sincipital encephaloceles are also common in aboriginal Australians, in parts of India, and in southern Russia. These lesions are more often seen in males.
