Cavernous malformation (cavernous angioma) |
|
|
An abnormal collection of blood-filled channels that resemble blood vessels. These vascular channels can bleed, resulting in formation of hematomas that can cause neurologic symptoms and deficits. Cavernous malformations tend to be multiple. Epidemiologic studies indicate that these lesions are more common in persons of Hispanic descent and in woman. Some neurosurgeons recommend that family members of patients with cavernous malformations have a screening MR scan of the brain. Surgery for these lesions is indicated only if they have bleed or are likely to bleed and if the lesions are located in a surgically accessible area. Cavernous malformations in areas of "eloquent brain" or in the brainstem are usually observed (and not operated) unless they have bled at least twice.
