What is the treatment for a cavernous angioma of the right frontal lobe?
Question:
Answers:
Cerebral cavernous angioma is a rare vascular malformation. There are at least three genes known to cause cavernous angiomas and they are inherited in a dominant autosomal manner. That is the patient has a 50% chance of inheritating the disease. One usually sees cavernous angiomas in at least one of the parents. Literature suggests that about 10% of patients with cavernous angioma have multiple angioma. Some angiomas are so small that they will not be detected by angiography and only when they become symptomatic do their presence become obvious. They do have a tendency to bleed, and when they are located in a quiet part of the brain, there will be no symptoms. As far as how dangerous these may be it depends on where the lesions are located.The angiomas will bleed, heal and rebleed. As they do this they grow in size. There is little that one can do about the bleeding. If the angioma is located in a place where surgery or intervention (coiling, etc) can occur, then these are possible ways of controlling bleeding. Coiling is a technique to clot off an aberrant vessel or aneursym. It is used by the neurosurgeons when the abnormal vessel or vascular mass is of the appropriate stuctural shape. The treatment of choice is surgical. The cavernoma and its surrounding gliotic and hemosiderotic tissue are removed using microsurgical techniques.
In all cases when more detailed medical information is required, you would be advised to consult a doctor or neurosurgeon.

1) Simple observation is an undesirable option in this particular situation where seizures are present.
2) Surgical excision if the angioma is in an accessible place and/or is relatively small.
3) Embolization, insertion of certain substances to occlude the blood supply. Effectiveness varies depending on several factors, including how many blood vessels are supplying the angioma.
4) Stereotatic radiation: a finely focused beam of radiation is delivered to the angioma to shrink or ablate it.
5) Cryotherapy or freezing: I don't think this is used anymore.
