Yes, it is possible for an arteriovenous malformation (AVM) to form later in life. An AVM is a tangle of abnormal blood vessels that can disrupt the normal flow of blood in the body, which can lead to a variety of health issues.
AVMs can be present from birth or may form later in life, usually during adolescence or adulthood. While the exact cause of AVMs is unknown, they are often linked to genetic conditions like hereditary hemorrhagic telangiectasia (HHT). Additionally, trauma or injury can also cause an AVM to form.
The most common symptom associated with an AVM is a headache. Other symptoms may include seizures, weakness, numbness, or vision changes. AVMs can also lead to other serious conditions, such as stroke, aneurysm, and brain abscess.
If an AVM is diagnosed, treatment options may include medication, surgery, radiation therapy, or embolization. Surgery is typically the preferred treatment option, as it is the only way to remove the AVM and prevent any future complications.
In conclusion, an AVM can form later in life and can lead to a range of health issues. It is important to seek medical attention if any symptoms develop to ensure that an AVM is properly diagnosed and treated.
