Cavernous Malformations (Cavernomas)

Cavernous hemangioma is known as cavernoma, cavernous angioma, and angioma. Located inside the brain but does not contain brain tissue,  lack of a large feeding artery or drainage vein,  benign vascular consisting of irregular thick and thin-walled vascular channels is a mass. It is generally 1-5 cm in size. There may be more than one in half of the cases. It may bleed, calcify (calcified), or become blocked with a clot (thrombosed). The cavernomas are filled with bleeding blood  elements from different periods. It has an incidence of 0.02-0.13%. It can be hereditary or it can occur later. They are low-flow lesions.

 

Symptoms:

With seizure (60%) (new seizure development rate 2.4%/year), progressive neurological impairment (50%), bleeding (20%) (total bleeding risk ≈ 2.6-3.1%/year), and _cc781905- It presents with 5cde-3194-bb3b-136bad5cf58d_hydrocephalus. It can also be found randomly.

 

Diagnosis:

It is not usually visible on angiography but can be demonstrated on MRI or seen on CT (especially with contrast). Surrounded by hemosiderin, which indicates minor bleeding. 

 

Treatment:

Treatment is controversial. Surgery is the best choice for symptomatic and accessible lesions, and radiosurgery can reduce the risk of bleeding in inaccessible lesions.
