	eMedicine - Brain, Cavernous Angiomas : Article by James C Jacobsen
		Cavernous angiomas belong to a group of intracranial vascular malformations that are developmental malformations of the vascular bed.
		Cavernous angiomas represent approximately 1% of intracranial vascular lesions and 15% of cerebrovascular malformations.
		Ultrasonography is not indicated in the diagnosis of cavernous angioma.

		Cavernous angiomas are clusters of abnormal blood vessels found in the brain, spinal cord, and, rarely, in other areas of the body.
		Cavernous angiomas are estimated to occur in approximately 0.5-1% of the population, or in 1 in 100-200 people.
		Cavernous angiomas in the spine are removed using laminectomy or unroofing of the vertebrae.

	Children's Hospital Neurosurgery - Cavernous Angioma FAQ
		A cavernous angioma is one of the types of malformations of the blood vessels in the brain that occurs relatively frequently in children.
		Lesions that are microscopically similar to cavernous angiomas can occur years following radiation therapy to the brain for the treatment of leukemia or tumors of the brain, implying that some type of injury to blood vessels may lead to the development of these malformations in susceptible individuals.
		If multiple cavernous angiomas are detected in the course of an evaluation, the decision regarding surgical excision becomes more difficult unless it can be determined which lesion is responsible for the development of the symptoms from which the patient may be suffering.

	Cavernous angioma - Wikipedia, the free encyclopedia
		Cavernous Angioma, also known as cerebral cavernous malformation (CCM), cavernous haemangioma, and cavernoma, is a vascular disorder of the central nervous system that may appear either sporadically or exhibit autosomal dominant inheritance.
		The incidence in the general population is between 0.1-0.5%, and clinical symptoms typically appear between 30 to 50 years of age.
		Not infrequently a CCM is accompanied by a venous angioma, also known as a developmental venous anomaly (DVA).

	USC Neurosurgery
		Cavernous Angiomas (CA); also known as cavernous hemangiomas, cavernous malformations, or cavernomas; are well circumscribed, benign vascular lesions composed of thin walled irregular sinusoidal caverns without intervening neurological tissue.
		Cavernous Angiomas comprise 10-15% of both intracranial and spinal malformations and are present in 0.3-0.5% of a large autopsy series.
		If your seizures are intractable (unable to control with multiple medications), your Cavernous Angioma is in a low risk, easily accessible area of the brain, and your neurologist has performed studies that indicated the lesion is causing the seizure, surgery for resection of the lesion may be indicated.

		Cavernous angiomas are characterized by a well circumscribed mulberry-like collection of sinusoids lined by endothelium, which unlike AVMs and capillary telangiectasias, are not associated with arteriovenous shunting or intervening brain parenchyma.
		Cavernous angiomas occur sporadically with no sex predilection, but may be familial in a small number of cases with autosomal inheritance and variable penetrance, particularly in patients with multiple concurrent lesions.
		Cavernous angiomas typically present between the third and fifth decades of life and are usually solitary.

	Cavernous Angioma
		A cavernous angioma is a blood vessel abnormality characterized by large, adjacent capillaries with little or no intervening brain.
		Symptomatic cavernous angiomas in children usually require treatment due to the high risk of future hemorrhage and greater seizure potential in children.
		The consequences of a hemorrhage from a cavernous angioma are rarely catastrophic, in contrast with arteriovenous malformations (AVMs) or

	Cavernous Malformation
		Vascular malformations or angiomas are localized collections of blood vessels that are abnormal in structure or number, lead to altered blood flow, and are not cancerous (nonneoplastic).
		Cavernous malformations are dilated blood vessels that are characterized by multiple distended “caverns” of blood that flow very slowly.
		The prevalence of cavernous malformations in children is estimated to be between 0.37 and 0.53% (up to 1 in 200 children have a CCM, whether symptomatic or asymptomatic), and approximately 25% of all diagnosed cavernous malformations are found in children.

	Angioma - Wikipedia, the free encyclopedia
		Angiomas are benign tumors that are made up of small blood vessels.
		They usually appear at or near the surface of the skin.
		Angiomas may appear anywhere on the body, and aren't considered dangerous (although they may be present as symptoms of another more serious disorder, such as cirrhosis).

	Cerebral cavernous malformation - Genetics Home Reference
		Cerebral cavernous malformations (CCMs) are collections of small blood vessels (capillaries) in the brain that are enlarged and irregular in structure.
		Cavernous malformations can occur anywhere in the body, but usually produce serious signs and symptoms only when they occur in the central nervous system (the brain and spinal cord).
		Mutations in the CCM2, KRIT1, and PDCD10 genes cause cerebral cavernous malformation.

	Vascular Malformations and Seizures - Neurosurgical Service - Massachusetts General Hospital
		Cavernous malformations are thought to account for 5 - 13% of all intracerebral vascular malformations and are frequently associated with intractable seizures.
		Cavernous angiomas are discrete vascular lesions comprised of multiple blood-filled channels lined by a single layer of endothelium but lacking in elastic or muscularis layers.
		Since the original description by Penfield and Ward, cavernous angiomas have been recognized as a cause of seizures, intracranial hemorrhage and progressive neurological deficit.17 Therefore, careful consideration must be given to the natural history of the cavernous angioma identified and the risk that it imparts to the health of the patient.

		A cavernous angioma (also know as a cavernous malformation or cavernoma) is a type of vascular malformation.
		The malformations are not visible by a conventional angiogram, and for this reason, cavernous angiomas are often referred to as angiographically occult vascular malformations (AOVM).
		Since cavernous angiomas are not visible on an angiogram, endovascular embolization is not possible.

	INTRODUCTION
		Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas.
		In intracranial cavernous angioma, angiography usually reveals the flecked lesion stain at middle arterial to late venous phases due to slow blood flow, delayed stain, or an avascular mass.
		In relation to the surgery of cavernous angioma at the cavernous sinus, bleeding was reported to be a major problem and preoperative differential diagnosis of extra-axial cavernous angioma from meningioma may be most important.

	Cerebral Cavernous Malformation, Familial -- GeneReviews -- NCBI Bookshelf
		Familial cerebral cavernous malformation is defined as the occurrence of CCMs in at least two family members, and/or the presence of a disease-causing mutation in one of the genes associated with CCM and/or the presence of multiple CCMs.
		Familial cerebral cavernous malformation is defined as the occurrence of CCMs in at least two family members [Verlaan, Davenport et al 2002] and/or the presence of a disease-causing mutation in one of the genes associated with CCM and/or the presence of multiple CCMs [Denier, Labauge et al 2004; Verlaan et al 2004].
		Cavernous malformations occur in two forms: a "sporadic" form, in which individuals usually present with one or two lesions and no family history of neurologic disease, and the familial form, characterized by multiple lesions and a strong family history of related neurologic deficits.

		CCM2 (603284) is caused by mutation in the CCM2 gene (607929), and CCM3 (603285) is caused by mutation in the PDCD10 gene (609118).
		Cerebral cavernous angiomas are to be distinguished from cerebral arteriovenous malformations (106070, 108010).
		Sporadic forms of cavernous angiomas manifest as unique lesions and familial forms as multiple lesions, which evokes a Knudson double-hit mechanism and would be consistent with the need for a complete loss of CCM1 function for the appearance of cavernous angiomas.

		If multiple cavernous angiomas are detected, the decision regarding surgical excision becomes more difficult unless it can be determined which lesion is responsible for the development of the symptoms.
		Although bleeding from cavernous malformations can cause serious neurologic deficits, in most cases these deficits recover over time and the hemorrhages are rarely fatal, unless the hemorrhage itself is large and located in a critical area.
