Complications & Outcomes
Survival rate
A survival rate is the proportion of people with a condition who survive, reported as a population-level statistic.
In short: Survival rate
- For large encephaloceles, a survival of around 55% has been reported (CDC).
- It is a population-level figure, not an individual prediction.
- It varies with severity, contents, and associated conditions.
- A child's own team gives the most relevant information.
What it is
It is the proportion of people with a condition who survive, expressed as a population-level statistic. It is the complement of the mortality rate and likewise describes groups, not individuals.
Understanding Survival rate
For large encephaloceles, a survival rate of around 55% (with a corresponding mortality of roughly 45%) has been reported by the CDC. As with any such figure, it reflects a particular group and varies with the size, contents, associated conditions, and presence of a syndrome. It is a population-level statistic that does not predict any individual child's outcome; the child's own care team, with knowledge of the specific findings, provides the most relevant and individualized information.
Why it matters
Understanding survival rate helps families interpret statistics with appropriate context — as descriptions of groups studied in research, not predictions for one child — and points them to their own team for individualized information.
Common questions
What survival rate is reported for large encephaloceles?
Around 55% (mortality roughly 45%), per the CDC.
Does this predict my child's outcome?
No — it is a population-level figure.
What does it depend on?
Severity, contents, and associated conditions.
Bottom line
A survival rate is a population-level statistic; around 55% is reported for large encephaloceles, but it does not predict any individual outcome.
