meningocele
Pronunciation: men-IN-go-seel
A type of spina bifida where the meninges protrude through a spinal defect, forming a fluid-filled sac.
Full Definition
A meningocele is a form of neural tube defect characterized by herniation of the meninges through a vertebral defect, creating a cerebrospinal fluid-filled cystic mass. Unlike myelomeningocele, the spinal cord typically remains in normal position, resulting in better neurological outcomes. This condition requires surgical repair and appears in neurosurgical consultations and birth defect registries. The term is often confused with the more severe myelomeningocele, making accurate usage critical in medical documentation.
Usage
Usage note: Distinguish carefully from myelomeningocele, which involves spinal cord herniation and carries worse prognosis.
