Dear Editor:

We read with great interest the recent report by Yeo and colleagues [2] describing two cases of de novo AVMs in children. Their cases and literature review provide further evidence that AVMs, especially in children, are dynamic lesions that can appear and change throughout a patient’s lifetime. Our recent publication [1], which was not included in their review, provides another case example of de novo formation of a pediatric AVM. Like the majority of patients described in their review, our patient had a history of a possible inciting event (a severe traumatic brain injury) that may have contributed to formation of the AVM. Additionally, the patient we described presented with seizures, as did one of the patients described by Yeo and colleagues. This reinforces the fact that new neurologic symptoms must be investigated with appropriate studies even in patients who have previously undergone neuroimaging.
