Cutis verticis gyrata

What causes cutis verticis gyrata?

The underlying cause of cutis verticis gyrate (CVG) is not well understood. The condition may be divided into 3 forms, based on whether it is isolated or it's association with specific underlying conditions:

  • Primary essential - refers to cases in which no other abnormality is present. In this form the cause is not known. While most of these cases appear to be sporadic, autosomal recessive and autosomal dominant inheritance have been described.
  • Primary nonessential - can be associated with intellectual disability, cerebral palsy, epilepsy (seizures), schizophrenia, cranial abnormalities (microcephaly), deafness, eye or vision abnormalities, or a combination of these. In this form, the cause may have an endocrinologic basis (caused by abnormalities of the endocrine system).
  • Secondary - associated with a wide variety of underlying diseases and treatments, which can be viewed here on Medscape's website. In these cases, the underlying cause depends on the associated disease or treatment.

What is cutis verticis gyrata?

Cutis verticis gyrata (CVG) refers to deep folds on the scalp that look similar to the folds of the brain. It occurs more commonly in males, and most commonly develops after puberty, but before age 30. It may occur alone (isolated CVG) or in association with a variety of underlying conditions or treatments, including neuropsychiatric disorders, eye abnormalities, or inflammatory conditions. While most isolated cases of unknown cause are sporadic, autosomal recessive and autosomal dominant inheritance with varying degrees of severity have been described. In cases associated with underlying conditions, the cause depends on the underlying condition. Management may include keeping areas within the folds clean, and/or surgery if requested for psychological or cosmetic reasons.
