[Duplicate origin of vertebral artery combined with brain tumor]

A 59-year-old woman was admitted to our hospital with complaints of disturbance of consciousness. CT scan revealed right ventricular tumor, which was homogenously enhanced by contrast media. Left vertebral angiogram demonstrated a duplicated origin of vertebral artery. Right ventricular tumor, which was diagnosed choroid plexus carcinoma histologically, was successfully removed. Nine cases of duplicate origin of vertebral artery were analyzed from the literature. Our reported case was first brain tumor case with duplicate origin of vertebral artery.
