The Neck Arteriovenous Malformations that May Rupture Anytime

Rupture-prone Neck AVMs

Abstract

This case illustrates the rare incidence of arteriovenous malformations (AVMs) of the head and neck in an adult male, possibly caused by the preceding trauma. A 30-year-old male with a chief complaint of headache worsened over the past day a sudden expansion of swelling over the back of the neck. The swelling was preceded by trauma to the neck two years ago. The contrast-enhanced computed tomography scan and computed tomography angiography of the head and neck concluded right neck AVM with aneurysms and contained hematoma. He was suggested for digital subtraction angiography and embolisation. Preceding trauma over the region was believed to have caused the neck swelling, and the ruptured aneurysm presented with a sudden onset of severe pain. It may progress to devastating complications if it is not treated in a timely manner.
