Core Terms & Classification
Cephalocele
A cephalocele is an umbrella term for any protrusion of the skull's contents — brain, meninges, or cerebrospinal fluid — through a defect in the cranium.
In short: Cephalocele
- Encephalocele is the most common and most familiar type of cephalocele.
- The term covers protrusions whether or not they contain brain tissue.
- "Cephalo-" refers to the head, and "-cele" means a pouch or hernia.
- Clinicians often use "cephalocele" generally and then specify the exact subtype after imaging.
What it is
Cephalocele is the broad category that encephaloceles and cranial meningoceles both belong to. It simply describes intracranial contents protruding through a skull defect, without yet specifying what those contents are.
Understanding Cephalocele
After a protrusion is identified, the team uses imaging to determine the precise type — for example, a meningocele (membranes and fluid only) versus a meningoencephalocele (with brain tissue). The general term may appear first in records or conversations, with the specific diagnosis added once imaging clarifies the contents and location.
Why it matters
Knowing that "cephalocele" is an umbrella term helps families read reports accurately and understand that a more specific diagnosis — which carries more meaning for the outlook — usually follows. It also explains why the same lesion might be described with different words at different stages of evaluation.
Common questions
Is cephalocele the same as encephalocele?
Encephalocele is one kind of cephalocele; the umbrella term is slightly broader.
Where do cephaloceles occur?
Anywhere there is a skull defect — front, back, top, or base.
Why might my child's report use both terms?
"Cephalocele" may be used generally, with the specific subtype named once imaging is complete.
Bottom line
Cephalocele is the general term for skull-content protrusion, with encephalocele being its most common form.
