Living with Cloverleaf skull syndrome

A form of early skull fusion that gives the skull a three-lobed shape and can affect the brain and development.

Understanding Cloverleaf skull syndrome

Isolated cloverleaf skull syndrome is a form of craniosynostosis (early fusion of skull bones) that gives the skull a three-lobed shape.

It involves several skull sutures. The shape ranges in severity, with a towering forehead, bulging temples, and a flat back of the skull. Features include downslanting eyelid openings, a flat midface, and very bulging eyes. It can be complicated by hydrocephalus (extra fluid in the brain), pressure in brain veins, developmental delay or intellectual disability, and a hindbrain herniation.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but the summary describes:

  • Three-lobed (cloverleaf) skull shape
  • Bulging forehead and temples
  • Very bulging eyes
  • Flat midface
  • Extra fluid in the brain (hydrocephalus)
  • Developmental delay or intellectual disability

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
