Living with Encephalocraniocutaneous lipomatosis

A rare condition present from birth that affects the brain, eyes, and skin of the head and face, with fatty growths under the scalp.

Understanding Encephalocraniocutaneous lipomatosis

Encephalocraniocutaneous lipomatosis (ECCL) is a rare condition that mainly affects the brain, eyes, and the skin of the head and face.

Most signs are present from birth and vary widely. A hallmark is a noncancerous fatty lump under the scalp covered by a smooth, hairless patch of skin. Many people have skin tags on the eyelids, hair loss, thin scalp skin, and eye growths called choristomas. About two-thirds have fatty tumors in the brain or around the spinal cord. These can cause seizures, muscle tensing, and intellectual disability from mild to profound, though about one-third have normal intelligence. There is an increased risk of a brain tumor called glioma.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Fatty lump under the scalp with hairless skin
  • Eye growths or cornea changes
  • Skin tags around the eyes
  • Calcium deposits in the brain
  • Missing corpus callosum (part of the brain)
  • Seizures and learning difficulties

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

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in FGFR1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
