A 55-year-old woman felt a left shoulder pain and then left upper weakness 3 days after the pain onset. The patient was introduced to our department because of suspected cervical spondylosis. Muscle weakness was detected in her left deltoid, biceps brachii, and radial flexor carpi muscles. Cervical magnetic resonance imaging demonstrated a significantly expanded left vertebral artery in the C4/5, C5/6, and C6/7 intervertebral foramina. A septum was found inside the dilated vertebral artery, and true and false lumens were confirmed. The septum, expanded false lumen, and shrunk true lumen were also observed on contrast-enhanced computed tomographic (CT) angiography. The nerve root compression symptoms were thought to be caused by the dissection of the left vertebral artery. The symptoms were spontaneously improved after 6 months. The false lumen was markedly reduced on contrast-enhanced CT. We report a case of extracranial vertebral artery dissection presenting with radiculopathy, along with a literature review.
