A case of arteriovenous malformation of the nasal dorsum

Abstract

Arteriovenous malformation (AVM) is a vascular malformation with an abnormal capillary shunt between the arterial and venous systems. AVMs can arise anywhere on the body, and are occasionally located in the head and neck. However, AVMs of the nose are considerably rare. Most cases of AVMs of the nose have no symptoms, but some cases show epistaxis and nasal obstruction. Furthermore, a differential diagnosis between hemangioma, lymphangioma, and AVM is important. In cases of AVMs, especially on the face, surgeons should consider cosmetic factors and choose an appropriate plan of treatment. We report the case of a 22-yearold male who presented with an asymptomatic, palpable mass on the nasal dorsum and was successfully treated with transcatheter arterial embolization and sclerotherapy.
