The true incidence of<unk> s is difficult to estimate because they are frequently misdiagnosed as other venous malformations.<unk> s of the brain and spinal cord (cerebral<unk> s (malformations) (CCM)), can appear at all ages but usually occur in the third to fourth decade of a person's life with no sexual preference. In fact, CCM is present in 0.5% of the population. However, approximately 40% of those with malformations have symptoms. Asymptomatic individuals are usually individuals that developed the malformation sporadically, while symptomatic individuals usually have inherited the genetic mutation. The majority of diagnoses of CCM are in adults; however, 25% of cases of CCM are children. Approximately 5% of adults have liver<unk> s in the United States, but most are asymptomatic. Liver<unk> s usually occur between the ages of 30–50 and more commonly in women. Cases of infantile liver cavernomas are extremely rare.<unk>  of the eye is more prevalent in women than men and between the ages of 20–40.
