Abstract

Although arteriovenous malformation (AVM) has been considered to be a congenital vascular malformation, morphologic differences associated with age have been indicated in the literature. We report a case of infant fistula-type AVM that developed into a nidus-type AVM 15 years later. This is the first report to document morphologic changes of AVM over time in 1 case. The present case suggests the possibly that AVM morphology may change with age and is an important when considering the history of AVM.
