Few articles reporting the anomalous origin of the right vertebral artery using imaging techniques, predominantly computed tomographic angiography and digital subtraction angiography, have been published.14 We present another rare case of a right vertebral artery arising from the aortic arch distal to the left subclavian artery incidentally diagnosed on gadolinium-enhanced magnetic resonance angiography of the neck on a 73-year-old patient who was being evaluated for carotid stenosis (Figure 1 and Figure 2). To the best of our knowledge, this is the first case diagnosed with magnetic resonance angiography.
