Encephalocele pathophysiology

Encephaloceles are rare birth defects associated with skull defects characterized by partial lacking of bone fusion leaving a gap through which a portion of the brain sticks out (protrudes). In some cases, cerebrospinal fluid or the membranes that cover the brain (meninges) may also protrude through this gap Pathology Encephaloceles, when congenital (most common) are a form of neural tube defect and occur due to a failure of fusion during embryogenesis of the cartilaginous neurocranium, the membranous neurocranium or viscerocranium 6 Definition: In encephalocele, the brain and meninges herniate through a defect in the cranium.

A cephalocele is defined as a herniation of cranial contents through a defect in the skull. Cephaloceles are classified according to their contents and location. We have reviewed a total of 112 patients with cephaloceles, 51 of whom had sincipital meningoencephaloceles (fronto-ethmoidal meningoencephaloceles). This group is distinctive in its demographic distribution, in the effect on growth. Encephaloceles are classified based on the location and type of skull defect. A commonly accepted system classifies encephaloceles as occipital encephalocele, encephalocele of the cranial vault, frontoethmoidal encephalocele, and basal encephaloceles (Table 1) Neuroglial choristomas are often actually an acquired encephalocele with herniation of brain into middle ear and mastoid; treatment is surgical, although tissue may adhere to facial nerve; determine relationship to CNS structures at operation or radiographically, not by histology (Laryngoscope 2000;110:1731, Ann Diagn Pathol 2004;8:252 Encephalocele is a sac-like protrusion of the brain and brain membranes (tissue that covers and protect the brain) through an opening in the skull. Approximately 375 babies are born each year in the U.S. with an encephalocele Encephalocele is a rare type of birth defect of the neural tube that affects the brain. The neural tube is a narrow channel that folds and closes during the third and fourth weeks of pregnancy to form the brain and spinal cord. Encephalocele is a sac-like protrusion or projection of the brain and the membranes that cover it through an opening.

An encephalocele is a protrusion of the brain and/or meninges through a defect in the skull (cranium bifidum) that is closed or covered with skin. Encephalocele is one of the three most common neural tube defects (NTDs) CONCLUSIONS: In the light of experimental data, some considerations have been undertaken considering the pathogenetic hypothesis findable in medical literature, stressing the possibility that encephalocele may be arranged as a post-neurulation defect and that, for taxonomic aims, it has to fit in a different group within cranial disraphims Nasal meningoencephalocele (encephalocele or cephalocele) is a herniation of cranial contents into the nose through a skull-based defect. Encephaloceles can consist of meninges alone, which are called meningoceles, or can also include brain tissue, which are known as meningoencephaloceles . This condition is uncommon, and congenital, traumatic, or spontaneous origins are possible Within the posterior fossa, it was bound to an occipital lobe encephalocele which issued as a diverticulum of the left lateral ventricle through a microgyric cortical defect in the territory of the left posterior cerebral artery.

Meningoencephalocele is a type of encephalocele, which is an abnormal sac of fluid, brain tissue, and meninges (membranes that cover the brain and spinal cord) that extends through a defect in the skull.

SUMMARY: Spontaneous lateral sphenoid cephaloceles arise from bony defects in the lateral sphenoid, in the absence of predisposing factors such as trauma, surgery, mass, or congenital skull base malformation.

Basal encephalocele is rare in adults. Congenital and acquired cases have been reported with regard to the developmental mechanism, and the pathology has not been elucidated in detail.

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) Encephalocele (Cephalocele; Encephalocystocele; Encephalomyelocele; Hydroencephalocele; Hydromeningocele, cranial; Meningocele; (... Pathophysiology Diagnosis allowing cerebrospinal fluid and/or brain to herniate. The encephalocele itself is defined as a herniation of part of the cranial contents through this skull defect. It may contain meninges (meningocele), meninges and brain (meningoencephalocele), or meninges, brain, and ventricle (meningoencephalocystocele).. Encephalocele is herniation of cerebral tissue, meninges, and cerebrospinal fluid (CSF) outside the confines of the skull. The condition is also termed cephalocele to encompass any combination of these intracranial elements. 1 Encephalocele has been recognized since antiquity; it was first depicted in ancient sculptures and later in medieval artwork to represent demonic creatures. 2, 3 Early.

CLOS Encephalocele represents one end of the spectrum of open neural tube diagnoses. With ultrasonography (US) scanning, the diagnosis is based on the herniation of a spherical, fluid-filled structure, more correctly diagnosed as a meningocele or brain parenchyma (encephalocele) beyond the calvarial confines Spina bifida is a set of malformations of the spinal cord caused by failure of closure of the neural tube and lack of fusion of the vertebral arches, soft tissues, and skin that cover the back. The lesion is usually in the lumbosacral area but sometimes it can be more extensive and may involve the entire spinal cord. In its mildest form, spina bifida occulta, the vertebral arches are absent.

Encephalocele is a clinically important birth defect that can lead to severe disability in childhood and beyond. The embryonic pathogenesis of encephalocele is poorly understood and, while usually classified as a 'neural tube defect', there is conflicting evidence on whether encephalocele results from defective neural tube closure, or is a post-neurulation defect The pathogenesis of encephalocele may be explained by separation of surface ectoderm and neuro-ectoderm in the midline just after closure of neural fold. It should be regarded as a late neurulation defect taking place during fourth gestational week (5, 6). Nasal encephalocele can be divided into sincipital and basal variety

The craniopharyngeal canal (CPC) is a rare, well-corticated defect of the midline sphenoid body from the sellar floor to the nasopharynx.

Cephaloceles are defined as congenital herniations of intracranial structures through a skull defect. If the sac contains meninges and cerebrospinal fluid, it is termed a meningocele. Encephalocele describes a sac that contains central nervous system (CNS) tissue. An AC contains meninges and neural rests. 1- Meningoencephalocele.
