Dynamic Changes in Arteriovenous Malformations (AVMs): Spontaneous Growth and Resolution of AVM-Associated Aneurysms in Two Pediatric Patients.

Arteriovenous malformations (AVMs) of the central nervous system are dynamic lesions that can change with time. One of the most clinically important concerns is the development and potential rupture of AVM-associated aneurysms. In this report, we review pediatric cases of de novo development of AVM-associated aneurysms in 2 children and present the relevant clinical and radiographic records. These 2 cases, coupled with a review of the current literature, offer insight into the risks of AVMs in children and underline the importance of timely treatment of appropriate cases.
