The medical disorder known as meningoencephalocele involves the protrusion or herniation of the meninges, which surround the brain, through a hole or gap in the skull. This disorder, which is a form of neural tube deficiency, can manifest itself in many areas of the brain.
Meningoencephalocele causes: Although the precise etiology of this condition is not always known, it is thought to be predominantly brought on by a confluence of hereditary and environmental factors. The neural tube arises early in fetal development and eventually gives rise to the brain and spinal cord. Meningoencephalocele is one of the neural tube abnormalities that can result from the neural tube failing to shut properly during the first few weeks of pregnancy.
Meningocele and meningoencephalocele have different characteristics.
Although both meningocele and meningoencephalocele are neural tube abnormalities, they differ in the protrusion's contents:
Meningocele: In this case, no brain tissue is exposed; just the meninges (protective membranes) protrude through the defect in the skull. The meninges and cerebrospinal fluid are both present in the sac-like protrusion.
Meningoencephalocele: In this disorder, the brain's tissue and meninges both protrude through the defect in the skull. Cerebrospinal fluid, meninges, and a piece of the brain are all present in the sac-like protrusion.
Meningoencephalocele treatment: Surgical intervention is frequently used to treat meningoencephalocele. Repairing the skull defect and lowering the risk of infection and further problems are the main objectives of surgery. The treatment entails carefully sealing the gap between the bones of the skull after re-inserting the herniated meninges and brain tissue. The procedure is frequently done soon after birth, though the exact timing may change depending on the circumstances.
The surgical correction may be more complicated in some situations if the meningoencephalocele is particularly large or linked to other serious brain abnormalities, necessitating the presence of a multidisciplinary team of neurosurgeons, neurologists, and other specialists.
The prognosis for meningoencephalocele might differ based on the size and location of the defect, the amount of brain tissue affected, and the existence of any concomitant neurological problems. It is vital to emphasize that meningoencephalocele requires highly personalized treatment. In order to manage this illness, early detection and rapid medical care are essential.
