Living with Acalvaria
An extremely rare condition present at birth in which the flat bones of the skull are missing.
Understanding Acalvaria
The base of the skull and the face are fully formed and usually look normal. A layer of skin covers the brain, and the brain's hemispheres look normal. This helps tell it apart from anencephaly. GARD lists onset as during pregnancy and as a newborn.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Missing skull bones (cranial defect)
- Brain development differences
- Small or absent cerebellum
- Extra little finger
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include bone and joint specialists.
- 3Ask which tests can help
Your care team will decide which exams and tests can confirm the diagnosis.
Care & treatment
- Care team
- Bone and joint specialists (orthopedists or orthopedic surgeons)
- Expert care
