Encephalocele Radiology Case Radiopaedia

  1. The MRI shows a right anteromedial temporosphenoidal encephalocele and a possible tiny left anteromedial temporosphenoidal cephalocele on the contralateral side. This is a frequent location for encephaloceles and is a check area, especially in cases of a suspected epileptogenic focus
  2. Frontoethmoidal encephaloceles are second only to occipital encephaloceles in terms of frequency, representing approximately 15% of all encephaloceles. They represent meninges or brain tissue herniating through a cranial defect in the anterior cranial fossa and typically result in facial deformity
  3. Cephalocele refers to the outward herniation of CNS contents through a defect in the cranium. The vast majority are midline
  4. Transsphenoidal and transethmoidal encephaloceles are rare but important lesions that cause various signs and symptoms, some characteristic and some misleading. Their diagnosis, both clinical and radiologic, may be difficult. Failure to recognize these lesions has in the past led to surgical misadventure, often resulting in meningitis and death
  5. Practice Essentials Encephalocele represents one end of the spectrum of open neural tube diagnoses. The incidence of encephalocele is estimated at 0.95 in 10,000 live births. The incident is..
  6. While the theoretical existence of this type of encephalocele has been recognized, no documented cases of transalar sphenoidal encephalocele are known to have been reported in the radiology or surgery literature

Encephalocele refers to the herniation of intracranial contents through the defect in the dura and calvarium [ 1 ]. Encephalocele is a rare entity in routine radiology practice; hence, a radiologist challenged with a case of cephalocele may find oneself lacking appropriate knowledge and reporting skills required to provide an optimal report It is thought to represent involuted true cephalocele (meningocele or encephalocele) connected to dura mater via a fibrous stalk

BACKGROUND AND PURPOSE: Temporal encephaloceles are increasingly visualized during neuroimaging assessment of individuals with refractory temporal lobe epilepsy, and their identification could indicate an intracranial abnormality that may be related to a potential seizure focus. Careful review by an experienced neuroradiologist may yield improved detection of TEs, and other clinical. 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-

Small temporal pole encephalocele: A hidden cause of normal MRI temporal lobe epilepsy STPE can be a hidden cause of TLE in a subgroup of patients with an initial report of normal MRI. Early identification of this lesion may help to select patients for presurgical evaluation and tailored resection Brain herniations into dural venous sinuses (DVS) are rare findings recently described and their etiology and clinical significance are controversial. We describe five patients with brain herniations into the DVS or calvarium identified on MRI, and discuss their imaging findings, possible causes, an Temporal lobe encephaloceles are an infrequent cause of seizures. Given that these lesions can be missed with standard imaging modalities, they are likely underdiagnosed upon initial medical evaluation. This diagnosis should be considered in patients with intractable seizures. If an encephalocele is An encephalocele (sometimes called a cephalocele or meningoencephalocele) is classified as a neural tube defect. The neural tube is the tissue of an embryo that becomes the brain, spinal cord and bones surrounding each. (Embryo is term used to describe a developing baby to the eighth week after conception) Nasal encephaloceles can be divided into frontoethmoidal and basal encephaloceles. Both conditions are very rare, but frontoethmoidal encephaloceles show a relatively high incidence (1:5,000) in Southeast Asia. The pathogenesis of encephaloceles may be explained by a disturbance in separation of sur

Radiology demonstrated the presence of a right parapharyngeal process obstructing the nasopharynx and oropharynx and extending to the right middle and posterior fossa, via the foramen ovale. This is a rare type of basal encephalocele, and has never been reported in an infant nor known to present with respiratory distress. The pathogenesis. Cephalocele is a generic term defined as a protrusion of the meninges with or without brain tissue through a defect in the skull. 1-2 A meningocele is a protrusion of only meninges and cerebrospinal fluid (CSF). An encephalocele is a protrusion of meninges, CSF, and brain tissue. An encephalocystocele contains meninges, CSF, brain tissue and. Post-traumatic fractures of the roof of the orbit are rare. 1 These are seldom related with orbital blepharocele or encephalocele. 2,3 Very few cases of orbital encephalocele have been reported, with a study published in 2010 stating the number such cases to be 25. 4 The first case was reported in 1951. 5 Orbital encephalocele is a result of frontal impact or lateral blow to the orbit. 3 A. Encephaloceles are more common in individuals who have a family history of neural tube defects such as spina bifida or anencephaly. In such cases, individuals might have a genetic predisposition to developing a neural tube defect and may develop an encephalocele. A person who is genetically predisposed to certain disorders may carry a gene (or.

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. Summary: Transalar encephaloceles are rare lesions that do not fit the standard classification of basal encephaloceles. Typically, these lesions present in adulthood, with nonspecific symptoms.

Lorber, in a series of 45 infants with occipital encephalocele and 10 with occipital meningocele, noted that 25 patients with encephaloceles died, including eight with hydrocephalus and three with microcephaly (87). Only four (9%) were neurologically normal, with two of these requiring shunting We report a rare case of a temporal bone encephalocele after a canal wall down mastoidectomy performed to treat chronic otitis media with cholesteatoma. The patient was treated successfully via an intracranial approach. An enhanced layer-by-layer repair of the encephalocele and skull base deficit was achieved from intradurally to extradurally, using temporalis fascia, nasal septum cartilage. Encephalocele Types. The disorder can be classified into a number of forms based on its location. Frontal Encephalocele. In this form, the midline of the upper region of the skull is affected. An extrinsic mass protrudes through the front region of the skull. It is also called Anterior Encephalocele and is the rarest form of the condition Encephalocele is an open neural tube defect that is most often present at birth. Normally, the neural tube folds and closes to form the brain and spinal cord around the third or fourth week of pregnancy, before most women even know they are pregnant. Encephalocele happens when the tube does not fully close during pregnancy

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).

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. Encephalocele is often found during a prenatal ultrasound. Treatment depends on the location of the encephalocele on the skull Radiology Case Reports. Volume 16, Issue 8, August 2021, Pages 2211-2213. Encephalocele is a congenital defect in the skull and the dura through which intracranial matter herniates outside. The transsellar, trans-sphenoidal variant is the least common subtype of encephalocele, and only a few cases have been previously reported.. Medical definition of encephalocele: hernia of the brain that is either congenital or due to trauma ABSTRACT-Previously utilized means of assessment of occipital encephaloceles are of limited value in defining the anatomy of the sac contents, determination of surgical candidates, and prognosis. Posterior fossa angiography has been utilized in 4 cases. It was helpful in determining the neural contents of the sac and particularly brain-stem positioning as judged from angiographic visualization.
