A rare central nervous system malformation characterized by herniation of meninges through a permanent defect in the skull. It is lined by arachnoid and contains cerebrospinal fluid, but no brain tissue. Signs and symptoms depend on the location of the lesion and are related to mass effect, skull deformities, or leaking of cerebrospinal fluid.

2025年2月7日 · Encephalocele, also known as meningoencephalocele, is a form of neural tube defect and a type of cephalocele where brain tissue and overlying meninges herniate out through a defect in the cranium.

2023年11月1日 · Encephalocele is a birth defect where brain tissue grows through an opening in your newborn’s skull. It’s a type of neural tube defect that happens when the top of the neural tube doesn’t close completely. The condition can be life-threatening, but surgery helps treat it.

A meningoencephalocele (or encephalocele) is a rare neural tube defect characterized by sac-like protrusions of the brain and the membranes that cover it through openings in the skull. These protrusions occur at any place along the midline of the skull, typically at the back of the head, much less commonly, in the middle or the front of the skull.

2022年5月2日 · 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.

2023年3月30日 · What are encephaloceles and meningoceles? An encephalocele is a rare disorder (neural tube defect) where the bones of a fetus’s skull (anywhere from the nose to the back of the head) do not close all the way resulting in a space through which the tissues surrounding the brain (cerebrospinal fluid and meninges) and brain tissue itself bulges.

2024年12月26日 · Encephalocele is a rare neural tube defect characterized by the herniation of intracranial contents through a skull defect. The presentation of this condition depends on the lesion's location, size, and content, with anterior and posterior types of …

Meningoencephalocele: This is a serious condition causing long term neurological (brain) problems. The sac like bulge that pokes through the opening in the skull has brain tissue and spinal fluid. The brain tissue in the sac is not normal.

2024年8月6日 · Nasal meningoencephalocele is also known as encephalocele or cephalocele. Nasal meningoencephalocele involves herniating cranial contents into the nose through a skull-based defect. These encephaloceles can consist solely of meninges (meningoceles) or brain tissue (meningoencephaloceles).

Meningoencephalocele is defined as the herniation of neural elements (usually a degenerative cerebral cortex), cerebrospinal fluid, and meninges through a congenital defect in the cranium. When meningoencephalocele is located in the occipital region, herniation of meninges, occipital lobes, and/or ventricles are common.
