Arteriovenous malformations (AVMs) are congenital vascular malformations which can be asymptomatic from birth to puberty. The agressive growing potencial of these lessions can make them symptomatic by pressing to surrounding tissues. The ideal treatment of an AVM is complete resection of the main nidus for the lesion. Incomplete resection of an AVM with a remnant nidus can be resulted with recurrences. In this case report we discussed an AVM case who treated succesfully by surgery with a lesion at the posterior side of the knee.
