An interesting case of arterio-veinous malformation in the neck.

An arterio-veinous malformation can be acquired and is rarely congenital. It usually presents with cosmetic deformity. If large it may manifest features of haemodynamic changes. Clinical assessment is the mainstay of diagnosis. Arteriography, MR angiography and rarely histopathology may help in clinching the final diagnosis. It is treated with wide excision after ligation of feeder vessels. Herein we present one such case of arterio-veinous malformation with review of available literature.
