Presentation
Neck swelling
Patient Data
Evidence of numerous tortuous serpentine intensely enhancing vascular channels are seen at the back of the right sided neck extending from the base of the skull down to the level opposite D2 vertebra, forming vascular mass like lesion measuring about 7 x 5 cm, the mass supplied mainly from the right subclavian artery and vein
Case Discussion
Arteriovenous malformations (AVMs) are characterized by an abnormal leash of vessels allowing for arteriovenous shunting. They can occur anywhere in the body but have a predilection towards the head and neck. There is a direct arteriovenous communication with no intervening capillary bed. They can be congenital or acquired.
