Brain arteriovenous malformations (AVMs) are abnormal connections between arteries and veins via the nidus (a tangle of abnormal vessels) without any intervening capillary network, within the brain parenchyma. Imaging plays a major role in the identification, grading and treatment of AVMs. The diagnostic criteria of brain AVM include a) the presence of a nidus and b) early venous drainage.
