We describe the case of a 44-year-old man with AVM occurring to the upper lip. A physical examination of the upper lip showed a soft mass with beat, measuring 3cmX1.5cm in diameter. T1 and T2-weighted MR imaging revealed low signal density mass showing flow void in the upper lip. Angiography confirmed perfusion of the AVM and revealed a feeding vessel from the right facial artery.

Abstract

Arterio-venous malformation (AVM) occurring to lips is rare. We describe the case of a 44-year-old man with AVM occurring to the upper lip. A physical examination of the upper lip showed a soft mass with beat, measuring 3cm×1.5 cm in diameter. T1 and T2-weighted MR imaging revealed low signal density mass showing flow void in the upper lip. Angiography confirmed perfusion of the AVM and revealed a feeding vessel from the right facial artery. After this confirmation, preoperative embolization with Gelfoam and Ivalon was immediately performed. Then the patient underwent complete surgical excision using Nd-YAG laser. On histological study, the specimen was composed of variably ecstatic and hyalinized veins and abnormally muscularized arteries. Thereafter the patient showed no evidence of recurrence more than 4 years later.
