Treatment Options for Cavernous Malformations in Children - Neurology

More Info

---

Cavernous malformations (CMs), also known as cavernous angiomas, are vascular malformations that can occur in the brain and spinal cord. They are composed of a cluster of dilated blood vessels that can lead to bleeding and neurological symptoms. In children, the management of CMs can be complex, particularly when they present with symptoms such as seizures or syncope (fainting), as in your son's case.


Understanding Treatment Options
1. Observation: In some cases, if the cavernous malformations are asymptomatic or if the symptoms are mild, doctors may recommend a watchful waiting approach. Regular imaging studies (like MRI) can be performed to monitor the size and characteristics of the malformations.

2. Medications: Antiepileptic drugs (AEDs) like Levetiracetam (known as Keppra) are often prescribed to manage seizures that may arise from the irritation of the brain tissue surrounding the malformation. While these medications do not treat the malformation itself, they can help control the symptoms associated with seizures. In your son's case, since he has experienced syncope, the AED may help prevent further episodes related to seizure activity.

3. Surgery: If the cavernous malformation is causing significant symptoms, such as recurrent seizures, neurological deficits, or if there is a risk of hemorrhage, surgical intervention may be considered. The goal of surgery would be to remove the malformation and alleviate the symptoms. However, the decision to operate depends on various factors, including the location of the malformation, the age of the child, and the overall health of the patient.

4. Stereotactic Radiosurgery: This is a non-invasive treatment option that uses targeted radiation to shrink the malformation over time. It is typically considered for lesions that are difficult to access surgically or in patients who are not good candidates for surgery.


The Role of Antiepileptic Drugs
Regarding your question about the role of the AED in your son's treatment, it is important to understand that while these medications are primarily used to control seizures, they may not directly affect the cavernous malformation itself. However, they can significantly improve the quality of life by reducing the frequency and severity of seizures, which may be related to the CM. If your son has not experienced any further episodes since starting the medication, it suggests that the treatment is effective in managing his symptoms.


Prognosis and Follow-Up
The prognosis for children with cavernous malformations varies widely. Many children can lead normal lives with appropriate management, while others may experience recurrent symptoms or complications. Regular follow-up with a neurologist and possibly a neurosurgeon is essential to monitor the condition and adjust treatment as necessary.
In conclusion, while the AEDs may not treat the cavernous malformation directly, they play a crucial role in managing the symptoms associated with it. If you have concerns about your son's treatment plan or if he experiences new symptoms, it is important to discuss these with his healthcare provider. They can provide guidance tailored to his specific condition and needs.
