Abstract
Arterio-venous malformation (AVM) is an uncommon abnormality, characterized by abnormally dilated pathologic vessels resulting in shunting of blood from arteries to veins without intermediary capillaries. The management of AVM is challenging because of high shunt flow and complex vascular anatomy. A 28-year-old female patient presented with a pulsatile occipital swelling. Sonographic findings of the AVM were confirmed on computed tomographic angiography, showing dilated, and tortuous vessels in the occipital region with feeders from the vertebral arteries and the right external carotid, which drained to the right internal jugular vein. She was treated by ligating the feeders.
