case_images: On neurological examination, there was an isolated oculomotor paresis consisting of left medial rectus, inferior oblique, superior rectus, inferior rectus with intact pupillary reflexes and bilateral especially left superior palpebral levator (Fig. 1A). Computed tomography (CT) angiography of the brain vessels showed left vertebral artery originated directly from the aortic arch, rather than the subclavian artery (Fig. 1B).
