The topic Cerebral Arteriovenous Malformation you are seeking is a synonym, or alternative name, or is closely related to the medical condition Arteriovenous Malformation of the Brain.

Quick Summary:

• Arteriovenous Malformation (AVM) of the Brain is the presence of abnormal arteries and veins in the brain that are enlarged and twisted. The condition is rare and is typically manifested in adults between 20-40 years of age
• An Arteriovenous Malformation of the Brain can occur in any part of the brain including in the:
  • Frontal, parietal, temporal, or occipital lobes
  • Cerebellum
  • Brainstem
  • The dura, which is the membrane covering of the brain
  • The spaces in the brain called ventricles; in which the cerebrospinal fluid circulates
• Although rare, AVMs are the most common vascular malformations of brain. It is believed to begin forming in the early developmental stages, when capillaries that connect arteries and veins are missing in parts of the brain, resulting in abnormal connections
• The size of this tangled structure is variable; it can often reach several centimeters in diameter. The symptoms of Arteriovenous Malformation of the Brain include headaches, numbness, weakness, and seizures. However, it is also possible for Brain AVMs to exist without presenting any symptoms
• The risk factors for this condition have not been currently identified. However, having a family history of brain vascular malformations and being a male, may pose some risk for developing this abnormality of the blood vessels
• The exact cause of Arteriovenous Malformations of the Brain is also not known. They may occur owing to abnormal development of blood vessels during gestation, and therefore, may be present at birth. The weakened, abnormal blood vessels can burst, leading to bleeding in the brain. In adults, a dural AVM can develop as a consequence of an injury/accident
• A healthcare professional may perform a physical examination, assess symptoms and evaluate personal and family medical history towards establishing a diagnosis of Brain AVMs. The affected individual is often referred to a specialist, who may conduct imaging studies, such as computed tomography (CT), magnetic resonance imaging (MRI) scans, and cerebral arteriography, to arrive at a final diagnosis
• Some potential complications from the disorder are bleeding in the brain, stroke, loss of vision, numbness, memory problems, difficulties with speech, weakness, rupturing of blood vessels and damage to the brain. Pregnant women with AVMs of the Brain may experience hemorrhaging
• The treatment option is determined by the size and location of the malformations. The affected individual may be prescribed medication for headaches and seizures. The abnormality can be surgically removed, the blood supply to the anomaly stopped with embolization, or radiation may be administered for treating Arteriovenous Malformations of the Brain
• The prognosis of Arteriovenous Malformations of the Brain depends on the size and location of the malformation. There is a possibility that a bleeding can cause permanent injury/paralysis, and be fatal as well. If no complications arise, the outcomes are generally positive
