A 58-year-old woman visited our department for paresthesia of the left occipital area and right arm, and intermittent weakness in both legs. CT angiography showed a right duplicated VA originating from the right subclavian artery. Axial CT demonstrated that the medial limb of the duplicated VA was located posteriorly to the right CCA and anteriorly to the vertebral transverse foramen. Sagittal CT revealed that the medial limb of the duplicated VA was located in close proximity to the CCA (). The patient was managed conservatively, and her clinical symptoms improved.
