Skin Diseases

Summary Summary

Cutis verticis gyrata (CVG) refers to deep folds on the scalp that look similar to the folds of the brain.^[1]^[2] 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.^[1]^[2] 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.^[1]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause

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:^[1]

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.

Statistics Statistics

The estimated prevalence of cutis verticis gyrata (with data from 1964) is up to 1 in 100,000 people in the general population. It has been estimated to occur in 0.5% (1 in 200) of people with intellectual disability in the United States.^[1]
