Abstract

Neck arteriovenous malformation (AVM) is an uncommon high flow vascular lesion. In the past, because of limitations in magnetic resonance imaging and sonography, invasive angiography was usually necessary for diagnosis and surgical planning. Here, we present a 33-year-old woman with neck AVM. Multidetector row computed tomography (MDCT) provided comprehensive preoperative information, including the anatomic location, feeding artery and draining veins of the lesion. This report demonstrates that MDCT has evolved into a mature technology that can be an alternative tool and probably a new paradigm in the diagnosis of and surgical planning for AVMs.
