Living with Porencephaly
A rare condition in which fluid-filled cysts or cavities form in the brain before or soon after birth.
Understanding Porencephaly
They form before or shortly after birth. How serious it is depends on the size, location and number of cysts. Common features include developmental delay, low muscle tone, seizures, a large head, weakness on one side of the body, speech problems and intellectual disability.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Fluid-filled cavity in the brain
- Seizures
- Weakness or paralysis on one side of the body
- Stiff muscles (spasticity)
- Intellectual disability
- Cerebral palsy
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Quick facts
It is usually the result of damage from an infection or a stroke, and in those cases it happens by chance. A familial form is caused by changes in the COL4A1 or COL4A2 genes and is autosomal dominant, meaning one changed copy of the gene is enough.
